Significantly expand the capacity of fisherman or hunter boat with a motor. If a person prefers to rest alone or in company with a close friend, there is no point in buying a large boat. Accordingly, it needs a compact and economical engine. The purchase of a low-powered (up to 3.5 l. s.) unit. It’s inexpensive and lightweight. In addition, such a motor does not need to register and obtain a certificate of shipowner. With the specified set of the vessel will have to settle for a modest stroke (8-15 km / h) and endure some other inconveniences. But the inflatable boat can be transported without a trailer and carriage on a usual passenger car.
On Russian market many Japanese, Chinese and American motor builders fight for the consumer. The range of models is so wide that the beginner has difficulty in choosing the right boat motor. Expertology experts have highlighted some parameters to pay special attention to.
How to choose a reliable boat motor
Many technical specifications for low-power boat motors are identical or differ slightly. There are therefore several points to be singled out.
Power. Among the low-powered boat motors, models with an index from 2.0 to 3.6 liters are popular. s.
- They are installed as the main motor if the boat is small. Besides, the number of fishermen is not more than 2 people, and it is required to overcome the distance not more than 10-15 km. In this case it is better to give preference to 3.0-3.6 liters engines. s.
- Often fishermen equip their boats and launches with a second engine, which is often used for trolling. Low power and economical consumption make it possible to set a minimum travel speed. In this case, the choice of motor depends on the size and construction of the watercraft.
Cooling system.In low-power boat engines there are two ways of cooling.
- The liquid cooling system allows to strain the unit to the maximum. Water from the reservoir flows through the motor’s channels, taking the heat away from the motor. The disadvantage of this design is fear of water pollution.
- If the engine is only air-cooled, the angler can visit shallow, overgrown waters without fear. But with prolonged high loads there is a risk that the unit overheats.
Gearbox. To move the boat in different directions there are several working options.
- Some models are equipped with full gearboxes, where there are one or more gears for forward movement, as well as the presence of reverse.
- The single-stage boxes look simpler. Speed of movement depends on engine speed, and for backward movement the engine can turn by 180 degrees.
- The presence in the gearbox of the neutral speed or overrunning clutch will be an important advantage for beginners. When starting the motor the boat will not start because the propeller will not rotate.
Expertology experts have carefully studied the boat motor market in the power segment up to 3.5 litres. s., Selecting the 11 best models. All of them were successfully tested in Russian conditions and received positive feedback from the owners.
