How to choose this product

petrol-in-board-engine

There are two types of inboard engine: diesel and gasoline. Gasoline inboards are relatively uncommon on leisure craft. Gas outboards are easier to install.

Applications

These engines are mainly used on fast powerboats.

Technologies

In a gasoline engine, an electric spark ignites a compressed air-fuel mix, causing it to explode. Modern versions have a four-stroke cycle. Two-stroke engines, louder and more polluting, are disappearing due to new regulations.

How to choose

Consider the motor's:
- Technology
- Fuel consumption
- Weight
- Power
- Torque

A indirect injection naturally-aspirated motor will be easier to repair because it is mostly mechanically controlled. However, its fuel consumption is higher than that of a direct injection model.

Advantages

- Greater power

Disadvantages

- Lower torque
- Fuel consumption
