Redo a trimmer for grass to a boat motor.

Alteration: a motor for a boat based on a trimmer for grass

Any fisherman who has an inflatable boat in stock sooner or later begins to think about acquiring a motor for her. But, having learned the price of ready.made solutions, many begin to look for alternative engine options for their boat. Fortunately, the craftsmen have already figured out how to redo the lawn mower, an electric screwdriver or a lawn mower in the boat engine. But the best option for these purposes is a gasoline trimmer for grass, which has in its design all the necessary mechanisms and elements.

First of all, it is worth considering the main advantages of using a trimmer for grass for the manufacture of a boat motor:

• The cost of a trimmer for grass is much lower than the cost of a finished engine for a boat;
• very economical fuel consumption;
• reliability during operation;
• light weight, which is very important when using a trimmer for grass on rubber boats;
• built.in translucent fuel tank, through the walls of which the level of gasoline is clearly visible;
• A rather sealed design;
• A hard shaft is installed in the bar;
• To control the unit there are finished elements (starter and gas).

All these qualities of the device put it in the first place, if we take into account other options for alterations. So, for a trimmer for grass (required by a power of 0.7 kW) to turn into a full.fledged boat engine, it is necessary to purchase a special set of nozzles or make them with your own hands.

Ready set of nozzles

At the moment, there are ready.made nozzles for a lawn mower, allowing you to convert your mower into a boat motor with minimal efforts.

The prefix already has a ready.made solution for attaching it to the gasoline engine of a trimmer for grass.

Also, the control handle with the muffler button is attached to the bar. The gas handle is made according to the likeness of the bicycle (meaning a bicycle with speed switching) and has a rattle that fixes the selected position.

This set even includes a special clamp, designed to fix the entire structure on the boat (on the vessel).

The nozzle for a trimmer for the grass is collected without difficulty, since its design is very simple. Only remains:

If you read the reviews on the Internet about this device, then they are mainly positive.

How to make a boat motor with your own hands from a trimmer for grass?

To assemble a motor from a trimmer for grass to a boat, the manufacturer will need to prepare the following equipment and materials:

• household lawn mower;
• clamp. If it is not, then you can use any other mount for reliable fixation of the motor on the boat;
• a sheet of duralumin, the thickness of which should not be less than 2 mm;
• welding machine;
• set of fasteners;
• set of screwdrivers and wretched keys.

To assemble a home.made rowing screw, the manufacturer will need drawings. They should indicate the exact dimensions of the blades and the method of fixing them on the axis.

It must be remembered that the lower the power of the drive used and the mass of the boat, the less should there be a blades. For example, a screw with blades 10 × 3 cm is suitable for a boat with a mass of not more than 120 kg.

After the preparation of equipment and a thorough study of drawings, you can start assembling homemade.

The work algorithm should look as follows:

• First of all, the manufacturer will need to finalize a bent shaft. First you need to dismantle the factory nut placed in a bobbin with a pre.wound fishing line. The nut itself in shape resembles a small 2-centimeter tube with internal thread. If necessary, it can be divided into 2 small full.fledged nuts. During the dismantling of fasteners, you need to be extremely careful so as not to lose them. If this happens, then finding another suitable fastener can no longer work;
• After dismantling the nut, you will need to dismantle the plastic pad located on the gas button. There are no roller bearings at the end of the standard curved rod. They are replaced by an ordinary bronze sleeve, which is often called a sliding bearing. It needs to be gently extracted. Before this, you will need to unscrew the nut, as well as remove the daily and metal shafts from the tube;
• Then you need to go to knocking out a plastic tread located on a flexible shaft. In the future, the steel pipe can be thrown away, since it will not be possible to align it with improvised means. It can be replaced by a duralumin pipe with the same diameter. It will need to install a bronze sleeve, which will need to be moved by a canvas using a hammer. Next, you need to take a plastic tread pre.trimmed in diameter, and install it on the pipe;
• The next step will be the manufacture of the screw. To do this, you need to cut out duralumin blades and sharpen their edges. After that, each blade will need to bend up 1 cm up so that the screw step is at least 10 cm. You can fix the finished device using a nut;
• Next, you need to install a bicycle speed switch on the boat motor from motorcycles, which will replace the standard plastic lining. After that, you will need to install a silencer that will take the engine exhaust away from the boat driver;
• To fix the boat engine from the lawn mower, you need to use two plywood sheets. After that, the shaft will remain using 4 screws for this. During the transportation of a boat motor from a trimmer for grass, the shaft can be removed.

After the homemade nozzle is ready, it will need to run into. To do this, prepare a fuel mixture of fresh gasoline and motor oil in a ratio of 40: 1. After that, you will need to pour the finished mixture into a standard boat engine tank, start it, and let it develop 1 full fuel tank at idle. After running in, a home.made boat motor from a trimmer for grass will be completely ready to work.

How to use a boat motor from motorcycles correctly?

Using a trimmer for grass, like a boat motor, the operator needs to constantly monitor the condition of the engine, and give him time to cool.

In addition, to extend the operating life of a boat motor from a trimmer for grass will help:

• Checking all the mounts available in the device. before each launch of the motor, you need to carefully inspect the latches that hold the engine elements from the trimmer for the grass;
• the engine is refueling from the trimmer for grass only with the gasoline and oil that was used for operation of motorcycles;
• timely cleaning and replacing the air and fuel filter of the engine;
• regular verification and timely replacement of the fuel pump;
• inspection and, if necessary, replacing the spark plug.

The regular ventilation of its standard cylinder will also help to extend the operating time of the boat ICE from a trimmer for grass. To do this, about once every 2 months, you need to twist the spark plug, and it is rarely possible to pull the starter cable 4-5 times. After the procedure, the candle can be screwed back to the place and continue the operation of the engine.

Necessary tools and materials

Manufacturing technology

Trimmers from a trimmer for grass are made in two ways: all parts, like a screw, are bought or produced with their own hands. The second decision will require more effort, but also less costs.

As such, a drawing is needed not for the drive itself, but in the manufacture of a home.made screw. The dimensions of the latter depend on the power of the drive and weight of the boat. A screw with parameters of 10030 mm is quite capable of moving transport weighing up to 120 kg.

• It is easier and faster to build a motor for a boat from a trimmer for grass, if you choose a model with a straight shaft. If a device with a curved shaft is used. a bent rod, it will have to be redistributed almost completely, since the steel cable in principle cannot transmit a delivery torque. In this case, the tube will need to be made with your own hands from the duralumin, then put a bronze sleeve into it, remaining after disassembling the bent shaft, and insert a re.fitted plastic holder.
• The homemade screw is cut out of the duralumin plate according to the drawing, the edges are pulled. The blade should have a curved shape, for this they are in turn bend 10 mm. The screw can always be adjusted by cutting or bending more than the blade, if its work during the tests is unsatisfactory.
• The screw is installed instead of a trimmer head. It is necessary to use a ring nozzle, otherwise the blades can breed the material of the boat or damage it. In the photo. screw fastening.
• Via the Internet you can find ready.made sets for remaking the lawn mower in the boat. It includes a drive and adapters to the shaft. Adapters are universal, which allows you to do without alterations of a curved bar and shaft. Often such a set includes a clamp. In this case, all work is reduced to the assembly of modification.
• Control. starter handle, can be used from a trimmer for grass. But if it is uncomfortable, which happens often, it is replaced by any suitable switch. from a bicycle, for example.
• Homemade boat motors from a trimmer for grass are fixed with clamp on the boat mince.

Trimmer boat from a trimmer for grass: step.by.step instructions for alteration

Almost every fisherman has a rubber inflatable boat at home. And naturally, everyone would like this mode of transport to be as fast as possible, comfortable and comfortable. If, in addition to the inflatable boat, you have a lawn mower in the farm, then you can design a home.made boat motor based on a trimmer for grass. Such a device is made quite easily and quickly, and its performance and reliability will quite be enough to move the boat over long distances. Step by step about the construction of a boat motor from motorcycles we will tell you later.

Using a trimmer for grass as a boat engine has a number of significant advantages and advantages.

The benefits of such a technical solution:

• Small cost: a trimmer for grass is much cheaper than a professional boat motor;
• small fuel consumption with sufficient performance;
• reliability and tightness of the structure, taking into account individual nuances of use;
• small dimensions and weight of the tool, which is also very practical and convenient for use in light boats;
• fuel control thanks to the transparent walls of the tank;
• Hard shaft inside the bar.

Engine power should be at least 0.7 kW. Ready.made nozzles for alteration (prefix for mounting to the engine, a special adjustable handle with a muffler button, fastening) can be purchased. After installing them on a trimmer for the grass, it remains only to connect the gas cable to the engine and connect the wires with the silencer.

How to make a boat motor with your own hands from a trimmer for grass?

To create a boat engine from a lawn mower, a direct rod is suitable. If the rod of a trimmer for the grass is curved, you will have to work on its improvement.

Algorithm occurs according to this algorithm:

• First, remove the standard nut (in the drawing below it is indicated by the number 2). Do not throw it away and do not lose it, since it is impossible to replace the factory parts with ordinary nuts.
• Spin the rest of the fasteners, pull out a deedwell and flexible shaft from the bar (in the drawing numbers 8 and 9).
• Choose a new duralumin bar with a slightly smaller inner diameter. Gently place a bronze sleeve in it (in the drawing).
• Cut the tread (part 0) to the required size and insert it into the bar.
• If the external diameter of the rod is too large for the engine, set it.
• Using a regular nut, fix the screw.
• The shaft fastening to the motor occurs using adapters. There are no universal drawings for this detail, since different models of trimmers have their own design features. You can order this part in a lathe or make it independently from plywood. The design will be attached with 4 screws.

If there is no way to purchase a ready.made set for remaking, which was mentioned earlier, the adjusting handle can be taken from a sports bicycle.

The screw can also be made independently from a piece of duralumin, using the drawing below:

A step is the distance from the blade to the horizontal surface. The angle of inclination is regulated by plots. To do this, the workpiece is pre.heated.

To refuel a motor from a trimmer for grass on a boat, use only high-quality fuel and lubricants. Dilute gasoline with oil in the corresponding proportion. The first 10 kilometers do not expose the engine with high loads. this will be the period of running. Depending on the engine power, a boat with such a motor can develop a speed of 5 to 8 km/h.

Below is a video that shows the work of such an unit::

Bicycle and scooter from a trimmer for grass

Often, owners of trimmers collect a scooter or a bicycle based on a garden tool. These home.made motorcosals are capable of speeding at 20 km/h, consuming, while the minimum amount of fuel.

A scooter or bicycle will need to be equipped with a strong platform on which the motor will be installed. It is best to cook a mount of a metal plate and several steel corners.

To transfer the force from the motor to the leading wheel of a home.made wheel, you will need to install a lead gear on it. In this case, the transmission of the torque is performed using the belt.

As a result, the manufacturer will receive a self-propelled 2-wheeled vehicle, which will be allocated by the simplicity of the device, as well as unpretentiousness to maintenance and quality of fuel.

Step-by-step instruction

All work is divided into several stages:

Preparation of the rowing screw shaft. To do this, the bar is disconnected from the trimmer body for the grass, the sleeves are unscrewed from it, playing the role of sliding bearings and the flexible shaft is removed. Then the curved lower part is cut off from the bar.

This method will no longer allow the benzotrimmer to return to its original state. Therefore, if in the future it is planned to use a trimmer for the grass for its intended purpose, then you should not cut the bar. It can be replaced by a pipe segment of stainless material of a suitable length. It is desirable that its diameter corresponds to the diameter of the bar. This will allow the use of complete bushings and shaft fastening to the engine housing.

When fixing the engine, it is advisable to use gaskets from the old auto.opening between it and the mounting elements. This will reduce noise and extinguish part of the vibrations.

It is difficult to determine the optimal shape of the rowing screw by eye. It is better to download one of the options from the network in advance and, according to its requirements, bend the blades. Two.lobed screws are easier to make and centered with than three.lobed. Therefore, for the first experiments, it is more reasonable to dwell on the option with two blades. With a screw diameter of the order of 100 mm and engine power in 3l.With. A similar design will be able to set the boat with a total mass of 120-150 kg.

The final step check the performance of the resulting boat movement.

Questions and answers

It is necessary to replace a flexible shaft with a steel pin due to a large load on such a system of transmission of torque. Under load, a flexible shaft due to twisting will not be able to rotate evenly, the boat will move with jerks. In addition, in this mode, the standard shaft of a trimmer for grass will not work for a very long time.

A purchased screw has a verified shape, which allows to achieve the maximum efficiency of the entire structure. In addition, boat screws are often sold complete with the necessary mounting elements of the bushings. This simplifies the alteration of the trimmer for grass to the boat engine, but requires certain financial investments.

Yes, this is possible, and even it will turn out to achieve a greater speed. However, in this case, the design will have to be finished with the gearbox, since the power of the engine of the trimmer for the grass is not enough to rotate the large screw. You can use a gearbox from a trimmer head. It will require a couple more stripes to fasten it. To extend the service life of the gearbox, it is necessary to monitor the constant presence of lubrication in its body.

How to use a boat motor from motorcycles correctly?

Using a trimmer for grass, like a boat motor, the operator needs to constantly monitor the condition of the engine, and give him time to cool.

In addition, to extend the operating life of a boat motor from a trimmer for grass will help:

• Checking all the mounts available in the device. before each launch of the motor, you need to carefully inspect the latches that hold the engine elements from the trimmer for the grass;
• the engine is refueling from the trimmer for grass only with the gasoline and oil that was used for operation of motorcycles;
• timely cleaning and replacing the air and fuel filter of the engine;
• regular verification and timely replacement of the fuel pump;
• inspection and, if necessary, replacing the spark plug.

The regular ventilation of its standard cylinder will also help to extend the operating time of the boat ICE from a trimmer for grass. To do this, about once every 2 months, you need to twist the spark plug, and it is rarely possible to pull the starter cable 4-5 times. After the procedure, the candle can be screwed back to the place and continue the operation of the engine.

Features of a homemade engine

When converting the motor, it should be borne in mind that they were developed to perform different functions. The trimmer for grass functions at large speeds and a small spinning moment, and the boat motor should do the opposite. Therefore, alteration of the device requires special tools and even a drawing.

The engine from a trimmer for grass is more convenient and easier to build, since it has a number of necessary components of the mechanisms:

• very economical engine;
• Impressed unpainted fuel tank, which allows you to easily control the amount of fuel;
• the presence of a starter and gas in the device;
• a rod equipped with a hard shaft.

Homemade boat motors from a trimmer for grass. options for alteration

You can make a boat motor from a trimmer for grass in three ways.

the vigor option is extremely simple, and does not require large financial investments. For work, you will need to buy a clamp necessary for attaching the engine to the boat transza, and the rowing screw. The latter can be sold both separately and in the form of a special kit. The set includes a special drive made of stainless steel, and several universal adapters required to connect a flexible shaft motorcycles. Often, the striper itself is also included in the set of the screw, therefore, before ordering the kit, be sure to specify what is included in it. The purchased kit can be used to install the engine from motorcycles to the boat. Work is carried out according to the instructions and takes away no more than half an hour.

The second option is more complicated in execution. For work, you will need an angular.type gearbox from a corner grinder, bearings and seals for mounting a motor, as well as a screw that can be cut from a solid steel sheet. This method makes it possible to increase the engine speed from the trimmer for grass. With practical use, such a design needs to be adjusted, for the implementation of which there will be a plot.

The third option is the easiest and consists in buying a special nozzle. Such a nozzle on a motorcycle for a boat does not require any alteration-it is enough to purchase a ready-made device and equip it with an existing trimmer for grass.

How to make a motor for a boat from a trimmer for grass. step.by.step instructions

Before making a boat engine from a lawn mower, you should carefully prepare. For work you will need:

• household trimmer for grass, with a capacity of at least 3 liters. With.;
• a sheet of duralumin or steel with a thickness of at least 2 mm. it will be required to make a screw;
• welding machine;
• fasteners;
• clamp or other device for fixing the motor to board the boat;
• Drill and corner grinder.

Immediately before work, you should study the scheme in detail. It should indicate the size of the elements required for the work, as well as the order and method of installation.

It will also be necessary to determine the dimensions of the rowing screw in advance. they depend on the maximum power of the drive used and on the mass of the boat in a loaded form. When choosing sizes, it should be borne from the fact that a screw with dimensions of 10 × 3 cm is capable of transporting a swimming product with passengers, with a total weight of up to 120 kg.

The procedure for the manufacture of an engine for a boat from a trimmer for grass is as follows:

• First of all, it is necessary to remake a bent shaft. From this goal, carefully remove the factory nut, originally placed in a bobbin with a fishing line. The nut has the shape of a 2-centimeter tube with an internal thread. The standard nut can be divided into 2 full details. At the same time, it is very important not to lose details, since each company-producing trimmers will equip its equipment with original spare parts. After extracting the nut, you will need to dismantle the plastic pad located on the gas button. There are no bearings at the end of the curved washer, and instead there a bronze sleeve is installed there, which also needs to be removed. After that, you need to knock out the plastic tread of the flexible shaft. The steel pipe available in the design can be thrown away, since it is not possible to get it perfectly without special equipment. Instead of a steel pipe, use a duralumin part with the same diameter. In the latter, install the previously extracted bronze sleeve and reliably impress it on a canvas using a hammer or a kiyanka. Next, take a plastic tread, cut it in diameter and mount it motionlessly into the pipe. If the outer diameter of the duralumin tube is larger, and the part cannot crawl into the hole for mounting on a motor boat, then it will need to be gripped until the optimal size is reached. If possible, then you can make a longer shaft by applying a suitable tube for this, and mounting a suitable bar of steel instead of a regular flexible shaft;
• At the next stage, you need to make a screw. To do this, from the duralumin sheet, it will be necessary to cut a strip, in size 10 x 3 cm or more. The edges of the cut strip must be sharpened. The screw step should be approximately 1 cm, so each of the blades should be bent upward by 10 mm to fix the rowing screw. In the manufacture of the screw, it is not necessary to use the venerable veneer, since when the screw impacts it will stop rotating;
• Next, you will need to replace the standard plastic overlay of the motor with a conventional bicycle switch. The direction of emission of exhaust gases can be changed by redrawing the muffler towards the rowing screw;
• At the last stage, you will need to attach the shaft to the motor from the trimmer for the grass. To do this, from ordinary plywood you need to cut 2 overlays that will be used to attach the engine to the head. It is necessary to fix the shaft with 4 screws that will clamp the part motionless. If necessary, then the shaft can be disconnected so that it is more convenient to transport the motor.

To run in a do.it.yourself boat engine from a trimmer for grass, you will need a full gasoline tank, which must be diluted with motor oil in a ratio of 40: 1. One liter of fuel mixture will allow you to swim on a boat about 10 km of path. The maximum speed of a boat with a motor from a trimmer for grass will be about 6–8 km/h. It should be remembered that the higher the transported weight, the lower the speed of the swimming agent will be.

Materials and tools

When selecting equipment, you need to pay attention to two things: power and voltage. These parameters are basic, and the quality of the finished electric motor depends on them

The power depends on the chosen drill (this is exactly the tool in this case), so first of all you need to choose this equipment.

When selecting a drill, it is necessary to focus on its power. This indicator should exceed one hundred and fifty watts. It is not worth taking a tool with less characteristics. In this case, the finished device will not work effectively in moving water (that is, swim with such an unit on the river will not work). It is best to use a battery.

The peoporator is equipped with a reverse, has several operating modes

This circumstance is important for the motor, which will move the swimming agent, since it will allow the future to control the speed of the electric motor

The second important parameter is voltage. You should not use batteries for eighteen volts. They are difficult to find and they are expensive. The best choice will be a drill working ten or twelve volts. Such a battery is relatively cheaper, and, most importantly, it is much easier to find on sale.

After choosing optimal equipment, you can collect materials. To create an engine, you must first get:

• Electric drill that will perform the function of the motor.
• Clamps with which the drill will be attached.
• Gearbox. You can use the element from the corner grinder, if it is supposed to install the motor on the boat transicure.
• Round pipes with a diameter of twenty millimeters.
• Profiled pipes (2020 millimeters).
• Round metal rod. It will be used to create an electric motor shaft.
• Sheet metal from which screws will be made.

You will also need some tools:

• scissors for cutting metal;
• welding device;
• corner grinder;
• electric drill with a set of drills;
• Electric screwdriver screws if a tree is used when creating a motor.

After all the elements are collected, you can start creating a boat electric motor with your own hands. The whole procedure consists of several stages. Work should start by creating a lifting mechanism for impeller. In order for the future device to work normally, it is recommended to carefully follow the instructions provided below.
