How to choose a quality engine
When choosing an engine, they are guided by the boat used
When choosing a reliable motor model, there are no minor details. When making a purchase decision, it is important to pay attention to the main criteria by which a gasoline engine is evaluated:
- power
- dimensions
- distance to propeller (daywood size)
- control system (tiller or remote)
- type and kind
Boat motors are:
- Two-stroke (simple design, but high fuel consumption and loud noise during operation)
- Four-stroke (economical, with clean exhaust, low vibration and noise level, but expensive and bulky)
The more powerful the engine, the faster and smoother the boat will move.
Engines, depending on the type, are divided into:
- carburetor (traditional, albeit outdated version)
- injection (provide confident acceleration, easy to drive)
Engine power varies from 2 to 35 horsepower and depends on the number of cylinders. So, single-cylinder options are suitable for quiet, short trips, and two-cylinder options are optimal for outdoor activities and driving long distances.
The weight of the mechanism also depends on the power: productive devices are the heaviest and largest. This indicator also affects the ease of use: light motors are easy to move from place to place, install on different boats. Massive but powerful devices usually become stationary.
