Boat motors are homemade. How to make a boat outboard electric motor by yourself

In order to independently collect a boatmotor, you need to understand its device. In addition, it should be taken into account that the tiller will be required to operate the model. In this case, it is more expedient to use the parts from an old boat engine. The trays for the engine are selected separately. Also, special attention should be paid to the fuel system. Some experts are able to fold the boat motor from a chainsaw or a trimmer.

The device of the simple motor

At the top of any boat enginethe motor is located directly. Through the fuel pump, it connects to the piston system. In addition, it should be noted that there is a special rocker in the boat motor. It is necessary in order to ensure the operation of the valves. In this case, much depends on the cubic capacity of the engine. On the pallet in the boat motor there is a clamp. With its help, it is possible to fix the model on board.

Fixers above the pallet are not always used. In some cases, gearboxes are also installed. Today there are a lot of Dadewoods. Under them is directly located the crankshaft, which connects to the central rod. Thus, the torque is transmitted to the lower gear. Through the special head, the screws rotate.

Chainsaw model

A boat motor from a chainsaw can be made, howeverYou need details from an outdated model. First, the engine of the device is extracted. It is installed immediately on the pallet. In this case, the fuel system for it can be selected the most common. In this case, the parameter of the limiting frequency does not exceed 1300 rpm. The rocker on these boat motors (homemade) will fit with three valves. However, special attention must be given to the type of convector.

With this part you can managetiller. After fixing the top plate, you can go to the deadwood. The crankshaft in this case is better to choose strong. In this case, the central rod must be borrowed from an old boat engine. At the end of the job, you only need to install the lower gear with the screws. For pumping water, an additional pump will be required.

Trimmer motor

Self-made outboard motors from trimmerare collected quite simply. First of all, experts advise to remove the handle. Replace it with a rod. Further it is important to make a pallet for the engine. In this case, you can use even a cast-iron plate. The engine must be secured very carefully. The fuel pump for the system can be used conventional. However, it is more expedient to select a camshaft for a strong one, otherwise it will not withstand the high loads. Dedwood is fixed in this case only after fixing the upper gear.

If desired, boat motors (homemade)you can install a thermostat. The clamp is mounted after securing the deadwood. To ensure that the motor gearbox is not loose, many experts recommend using a special rubber gasket. Screws in the model must be fixed on a vertical shaft.

Model of motoblock

Collect self-made boat motors from the motor blockit is rather difficult, but it is possible. If we consider electrical modifications, the starter is first extracted from the device. It is also necessary to disconnect the motor. If a four-stroke modification is used, the fuel system will be the most common. Water pump in this case it is important to choose a quality one. In turn, you can take a deadwood from an outdated boat engine. To fix the fuel pump, many use different fixatives. The easiest way to consider it as staging it over the carburetor. At the same time, he should not touch the yoke.

Crankshaft on boat engines (homemade)must be fastened over the upper gear. At this stage it is necessary to check the strength of the clamp. The pallet, in turn, should not block it. The water pump in this case is installed under the deadwood. In order not to interfere with the operation of the lower rod, many experts recommend using special springs. After fixing them, only fix the screws and tiller.

Devices with two-way flywheel

Make a boat engine with a two-way flywheelwith their own hands - the task is not easy. The engine in this case is more expedient to choose a two-stroke type. Thus the rocker under it should be designed for three valves. Also before the installation it is necessary to check the strength of the pushers. They must withstand a pressure of at least 3 bar. In this case, you can hope for stable operation of the engine. The pallet in this case must be mounted under the clamp. For convenience, it can be fastened with screws and then use a sealant. After securing the tiller, the deadwood is connected. The protection of the propeller screw is installed last.

Models with two-stroke engines

Make a boat engine with a two-stroke engineYou can only use your own hands if you use a crankshaft with a diameter of at least 60 mm. Otherwise, it can not withstand the load. The flywheel in this case can be chosen the usual. At the same time, the fuel pump must withstand a pressure of at least 3 bar. The experts advise installing the rocker arm on only three valves. The thermostat is mounted on boat motors (homemade) if desired.

Exhaust valves in the system are installed more oftenall aluminum. Cooling devices are available today. The simplest variant is considered to be a water modification. To do this, in the pallet should be in advance to provide for fences. The pushers above the engine must be installed last. The deadwood for the push-pull modification is suitable with a 120 mm rod.

Devices with four-stroke engines

Assemble a self-made outboard outboard motor withfour-stroke engine can, however, have to use parts from another model. In particular, it is necessary to select the clamp for the device separately. It should also be noted that the rocker requires four valves in this case. In this case, the tank is installed under the fuel system near the pallet.

Dedwood for the engine are selected, as a rule,on two stock. In this case, the crankshaft must be selected separately. Connectors in such devices are installed quite often. The tiller should be attached directly to the flywheel. Fixators for this are best used steel. Without welding in this case, it is quite difficult.

Modifications on the manual starter

Homemade boat motors (bogs) withmanual starters are quite common. These components are installed near the camshaft. In order to fix them, you need to use a rubber gasket. At the same time, there must be at least four screws. If we consider four-stroke engines, then there starters, as a rule, are installed electronic type. However, for hand-held modifications manual devices are ideal.

The model with the protected reducer

Boat motors with a protected gear ontoday are quite popular. In order to assemble them independently, it is necessary to select an engine with a power of at least 3 kW. The starter in this case is suitable for hand type. First of all, the clamp for the engine is cut out. Only after this you can proceed to install the fuel system. The thermostat, if desired, is mounted on the rocker arm.

The next step is fastening the reducer. To ensure that the rocker does not twitch during operation, it is possible to lay a gasket under it. Install pushers on the pallet, and for this you will need to use a welding machine. The top rod in this case is important to attach under the clamp. That the pressure does not deform the pallet, many experts advise to install additional supports.

Devices with an anti-cavitation plate

Boat motors with the help of anti-cavitationthe plates are managed quite comfortably. In this case, it is necessary to begin work on collecting the device with the engine secured. Only after this fixers are welded. To fix the fuel pump, you can use the screws. In this case, it is not necessary to install the gasket. Special attention should be paid to the fuel system. It must be fastened next to the water piston. Anticavitation plate is fixed near the connector. However, it should not touch the pallet. In the end, it remains only to install deadwood.

Motor with gearbox

Boat motors with gearboxes assemblepretty hard. In this case, the connector must be selected high-quality. In turn, the engine can be used four-stroke. The pushers for the system are set quite wide. Mount the gearbox at the top flange. In order to avoid short circuits, all wiring should be carefully hidden. In addition, you should take care of a good water pump. To seal the upper stem from the carburetor, you can use a sealant.

Model with a reverse lock

In order to assemble a motor with a rear lockthe engine must first be secured. After that, the tiller is connected to the plate. The fuel system can only be installed after the rocker arm. In order not to clamp the carburetor, many advise using gaskets.

The backstop must be attacheddirectly under the clamp. For this purpose, it is necessary to use a welding machine. After that, it remains only to fix the deadwood. If the outboard motor is installed with the gearbox, the retainer can be located directly in it. However, it is rather difficult to do this due to the fact that you have to saw the block body.
