The choice of outboard motor depends on the conditions of its operation, and they may not be the same. The engine can be installed on a fishing boat, on a small boat for water travel or even on a yacht. Accordingly, motors for different floating facilities will be needed with different technical characteristics.
With the same heat group, you can achieve up to 55 horsepower. Proven Engine produced over many years, of which many advantages and few defects are well known. Relatively easy to repair. Slightly above top speed and very comfortable cruising speed. Package this boat with this engine if you don't expect big loads and you don't have a driver's license are correct, speeds are good, fuel consumption is good, even if the biggest of the four times did it better with better technology.
How to choose a boat motor
First of all, the outboard motor is selected by power. They select it, guided by the parameters of the boat or boat. The power of the installed engine should be slightly less than the maximum allowable indicator indicated in the technical specifications of the floating craft - an engine that is too weak will not cope with the control of the vessel, exceeding the norm will lead to overload.
Motors differ in control. For starting, they can be with a manual start (manual starter) and electric, for controlling the movement of a floating facility - with a tiller or remote drive.
When choosing an engine, also pay attention to:
- on the number of cylinders;
- type (two-stroke or four-stroke);
- along the length of the deadwood ("legs" of the motor);
- on the type of ignition (contact or electronic).
Manufacturer
The choice of the manufacturer is of great importance. Among them there are such well-known companies as Suzuki, Yamaha, Tohatsu (Nissan), Mercury, Honda. AT recent times many different Chinese-made engines appeared.
Among domestic outboard motors, models should be noted:
- "Veterok" of the Ulyanovsk plant;
- Samara "Whirlwind";
- motors "Salyut" and "Neptune" of the Moscow plant.
Perhaps Honda is a leader in the production of outboard motors. The quality and reliability of the products of this brand is at a very high level.
Domestic engines are attracted by a rather low price. Unfortunately, they have practically no other advantages. The reliability of the units themselves and spare parts for them leaves much to be desired.
Power
Approximately, motors by boat power can be classified as follows:
- from 2 to 6 horsepower - for small boats moving at low speed;
- from 8 to 15 hp - well suited for boats with a length of 3-3.5 m, you can move over considerable distances;
- over 20 hp - allow you to quickly move around the reservoir, designed to carry a large load.
2-6 hp
Such engines develop the speed of the vessel from 5 to 10 km / h. They are designed for sailing on small lakes or calm rivers. It should be noted that the operation of a motor of too low power is in some cases unsafe - a weighty boat can be blown away by the wind.
As a rule, motors have the following characteristic differences:
- number of cylinders - 1;
- type - two-stroke and four-stroke (but more often two-stroke);
- built-in;
- key type protection;
- light weight.
With a low-power engine (from 2 to 6 hp), the boat is unlikely to be able to enter the mode (planing is the ability of the boat to rise above the water when moving, and the boat moves almost parallel to the surface of the water). Long-term operation at full throttle contributes to the rapid wear of a low-power unit, and idle speed is very unstable due to the fact that one cylinder is working.
Plus motors up to 5 hp is that it is possible to move on floating facilities without having a certificate for the right to drive.
8-15 HP
With such motors, the boat can already go on planing. Fuel consumption can reach up to 6 liters per hour at high loads, in trolling mode (method fishing) consumption is much less.
These engines are characterized by:
- the presence of two cylinders;
- manual gas control;
- weighing from 25 to 55 kg;
- rather high cost relative to the weakest units;
- ensure the speed of the boat or boat from 3 to 30 km / h (at the same time there is the possibility of trolling and gliding);
- controlled with a tiller.
Over 20 hp
Such engines are not very popular with fishermen due to their low efficiency, but for boats and yachts such units will be just right. With a powerful motor, trolling is difficult, but water skiing can be provided.
Motors often have:
- electrical starting system;
- four-stroke engine type;
- two cylinders.
The weight of the lightest 20-horsepower motor is at least 45 kg, but they are usually even heavier. The price of an imported engine starts at 80,000 rubles.
2-stroke or 4-stroke motor
Each of these types has its own advantages and disadvantages. But for powerful engines, a four-stroke version is more preferable.
two stroke motor
- consumes more fuel (about 20 percent compared to 4-stroke);
- its operation requires mixing fuel and gasoline;
- it works as smoothly as a 4-stroke;
- more noisy.
Four stroke motor
- has a better resource and less likely to need repairs;
- gaining momentum faster;
- works more stable at idle;
- not very picky about the quality of fuel.
Despite a number of advantages of a 4-stroke engine, a 2-stroke is more interesting when traveling short distances. Then, two-stroke motors have a lower cost and relatively light weight.
Engine fixation
From the installation of the motor on the transom of the boat depends on how it will behave in various conditions. If the engine is set too high, air can be caught in the blades, if the position is too low, the resistance to the movement of the boat increases.
The installation is carried out on the transom with clamps, but there is still free play - the motor can be lowered and raised. Rigid fixation leads to the fact that when hitting an obstacle, the engine can be damaged. Therefore, the installation is carried out so that when hitting an obstacle, the engine can tip over.
Engine Tilt Levels
The motor must be mounted on the transom in the center, and the clamps must be screwed up to the stop. It is important to choose the right angle of the motor, its incorrect installation increases the resistance to movement and reduces power.
The angle of inclination is checked at a speed corresponding to the average value. This takes into account the trim of the boat (inclination relative to the surface of the water). The trim is considered correct if, in the state of immobility of the floating craft, the bow is raised by 3-5 degrees. A high nose can cause the boat to capsize, a low angle increases the load on the motor, controllability is lost.
Rating of popular outboard motors with prices
Among all manufacturers of outboard motors, the following brands have proven themselves best:
- Honda;
- Suzuki
- Yamaha;
- Mercury;
- tohatsu.
When comparing 15-horsepower engines best performance Honda showed in all respects, Suzuki and Mercury engines are a little inferior to it. But among all the Honda BF-15 models, it turned out to be the most expensive (about 150,000 rubles).
Average prices for other brands of 15 strong engines:
- Suzuki DF-15 - about 130 thousand rubles;
- Tohatsu M15D2 S -95 thousand rubles;
- Mercury 15m - 95 thousand rubles;
- Yamaha 15FMHS - 100 thousand rubles.
Yamaha
YAMAHA MOTOR is the world's largest manufacturer of boat engines. It produces engines of different power starting from 2 hp. and ending with 250 hp. The company gives a 2-year warranty on all products.
Suzuki
Suzuki outboard motors are known for their excellent performance and reliable quality. The company enjoys the most modern technologies in the development of their products. Models of outboard motors with power from 9.9 to 40 hp have become the most popular.
Tohatsu
Tohatsu has existed in the gasoline engine market since 1922, the corporation released the first outboard motor in 1956. The company's products are of impeccable quality. Tohatsu motors are rightfully considered one of the most environmentally friendly in the world.
Mercury
The American corporation MercuryMarine holds a leading position in the production of outboard motors. Mercury engines are quiet, economical and easy to drive. The company's products meet all the requirements of world standards.
Which outboard motor to choose from Chinese
Among Chinese products, the choice is not so simple, especially since boat motors made in China are of good quality. When choosing an engine, you should be guided by the availability of a service for the repair and maintenance of motors. In particular, SIA-PRO in Russia has such a service. It should also be noted the good quality of products from Parsun, Troll and Hondex (HDX).
In order to avoid problems during the operation of the outboard motor, it is worth adhering to a number of rules:
- It is not necessary to check the performance of the motor at a constant full throttle, especially on thick grass and stones in shallow water. Such trips can result in damage to the propeller shaft or failure of the gearbox.
- The mixture of gasoline and oil must be in the right proportion. Violation of the proportion leads to the failure of parts of the fuel system.
- It is necessary to change candles in time, guided by factory standards. It's a good idea to always have a couple of candles in stock.
- It is necessary to regularly check the presence of a jet in the control hole of the cooling system in order to avoid overheating of the motor.
- You must have spare pins with you. If the key breaks, it can be replaced on the way and move on.
It should not be forgotten that on the water the circumstances are somewhat different than on the road. It may happen that there will be no one nearby and there will be no one to help.
