Teach you to understand overboard motor

The overboard motor is like the heart of a yacht. The quality of the engine depends mainly on power and economy, that is to say, the engine should have good power, good acceleration and low fuel consumption.

Outdoor boat engine are mostly low-speed engines.

Survey

Generally, marine engines belong to the category of low-speed engines. The speed of engines is usually below 800rpm (except for special speedboats), because marine engines need to match propellers. Considering the matching efficiency, too high engine speed is not helpful for this. Other large cargo ships or cruise ships use heavy oil as engines, which are usually two kinds of engines. Stroke low-speed machines, of course, also have high-power four-stroke medium-speed machines, medium-speed machines are generally used as auxiliary engines on ships for power generation and other uses.

How to Choose Marine Engine

Installation Differentiation

The engine configuration of private yacht directly affects the engine performance. How to compare the engine configuration?

According to the installation method, yacht engines can be divided into:

inboard engine

The engine is mounted on the inside of the ship, mainly on large yachts.

Stern drive Engine

The yacht engine is installed on the inside of the ship and the propeller is installed on the outside of the ship. It is a new type of stern engine, which is driven horizontally in the cabin by a propeller connected vertically downward through the stern engine. Yachts are mostly equipped with small and medium-sized vessels abroad. Its characteristic is that it combines the advantages of the ship's interior engine and the ship's exterior engine. With low fuel consumption, is one sixth of the same horsepower trailer; maintenance is very convenient, the propeller can be lifted; small size, fast speed, cost-effective features.

overboard motor

Fixed to the outside of the ship. It is a kind of unloadable power device suspended on the stern board of a boat and boat, which can propel the boat and boat to sail. The utility model has the advantages of compact structure, light weight, convenient disassembly, simple operation and low noise, and is suitable for use in inland rivers, lakes and offshore waters.
