trimmer for grass for a rubber boat

It is known that fishermen are very resourceful people. If the owner of the rubber boat has a desire to increase the speed of the movement of his vessel, but there is no sufficient amount for this, then the installation of a trimmer for grass from the lawn mower will help while the cost of a lawn mower is much less. The power of a trimmer for grass is quite decent for installation on a rubber boat.

Advantages of a trimmer for grass when installing on a rubber boat:

Beginning fishermen have questions about installing the device on their boat.

Is it possible to put a trimmer for grass on a rubber boat

The answer to this question is yes, you can. This is an inexpensive (compared to a full.fledged boat engine) a way to increase the speed of movement around the reservoir than buying a full.fledged motor. To use a trimmer for grass from the lawn mower as a boat engine, you need to modernize it slightly. There are two ways to prepare the device for installation on a rubber boat. The first way is to purchase special nozzles, and the second is to make them yourself. The finished set of nozzles solves all your difficulties with installing a trimmer for grass on a boat. Such a set usually includes:

Rowing screw; 2. The prefix-pumping. It is the lower part of the boat engine (without an engine), on which a trimmer is attached for grass from the lawn mower; 3. Adapters for installing different types of trimmers; four. Rumpel. handle for control. Equipped with a muffler button; 5. Clamp. With its help, a trimmer for grass is attached to the vessel of the vessel.

Self.manufacture of a trimmer for grass is possible when using a motor from a lawn mower with a straight bar and a hard shaft. To do this, you only need to make a rowing screw. The raw materials of manufacture can serve as stainless steel or duralumin. The blades must be bent, the edges of the screw should be sharpened. In the case of using a motor with a curved shaft, it will have to be completely redone and it will take much more time.

The advantages and features of the alteration of the trimmer for grass in the boat motor

The use of the lawn mowing available on the farm has a number of advantages. Firstly, the owner of the boat will not overpay for an expensive motor purchased in the store. Secondly, the motor for a boat from motorcycles consumes much less fuel than specialized boat engines. Thirdly, the engine from the lawn mower has an order of magnitude smaller dimensions than the boat engine purchased in the store. There are a number of other factors forcing fishermen to use a trimmer for grass instead of a boat motor.

  • high reliability of engines of modern trimmers;
  • complete tightness inside the body;
  • the presence of all the elements necessary for the control of a home.made engine;
  • The presence of a built.in tank.

Thanks to all these factors, the boat motor from motorcycles is most popular among enthusiasts.

In the process of processing the engine from the lawn mower to the boat engine, it is extremely important to consider that this power unit was produced for other purposes. Trimmer engines operate at small torque, but, at fairly large speeds. In the case of a specialized boat engine, everything happens the other way around. In this regard, to remake a motor from a trimmer for grass, you will need to prepare drawings, equipment and observe a certain procedure.

Despite some difficulties in converting, it is in the trimmer that all the details necessary for the manufacture of the boat engine are a built.in starter and a gas lever, a rod with a hard shaft and a translucent fuel tank.

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 first 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.

Principle of operation

The trimmer for grass has a higher speed speed of the blades, which makes it possible to move around the water with higher speed, which will begin to proceed with fishing faster than with a motor. Everyone saw how the work of a trimmer for grass. how the lawn and ordinary grass cuts, but here, its blades are turned the other way and at the same time, performs the function of the most economical motor.

And the most important thing is that absolutely everyone can control it. the most important thing is to understand, the higher the blades themselves are to the surface of the water, the faster the speed of turnover and thereby. higher speed.

But if the trimmer for the grass is lower, the speed will be lower. But the most important drawback of the trimmer compared to ordinary boat engines is that they are very loud and you should not use them to the full, if you do not want to frighten off the fish.

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.

Unfortunately, the four-stroke engine Elmos EPT-40F did not justify the hopes assigned to him. Either the poor.quality metal of the sleeve, or I overloaded it without running it properly, but the compression decreased quickly, difficulties began with launch (subsequently dashed on the sleeve, were found). In general, it was risky to take such an engine planned a serious campaign. And two weeks before the start, a difficult decision was made to buy and quickly convert another brand brand mower. So there was a return back to the two.stroke “shindai”, only a little greater power (model Shindaiwa C230. 1.2 l.With). I managed to redo it, but rolled up on the route 🙂

Questions and answers

Why is it impossible to save a full.time flexible shaft in the bar.

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.

Than the factory screw from the store is better than a homemade?

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.

Is it possible to use a screw more than 100 mm diameter?

lawn, mower, boat

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.

After the procedure, the candle can be screwed back to the place and continue the operation of the engine.

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.

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.

How to Make a Homemade Boat Motor for Under 90.

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.
