How do you use your RIB boat? 

The primary use of your RIB boat determines which type of engine you should choose. 

Tender / rubber boat for anchorage 

• Typical engine selection: 2-10 hp, either petrol or electric. 

•  Main factors: Low weight, easy handling and storage. 

Example: If you have a larger yacht and use a RIB as a tender, a lightweight electric motor or a small four-stroke gasoline engine be the most practical choice. A Temo 450 or one Mercury F6 are popular choices. 

Water sports & speed boating 

• Typical engine selection: 70-250 hp, 4-stroke gasoline engine. 

• Main factors: Fast acceleration, high top speed, powerful torque. 

Example: If you want a larger RIBs that can tow water skiers and tube-rings at high speed will Mercury Pro XS 115 hp or Mercury 150 FourStroke give you the right punch. 

Transport & fishing 

• Typical engine selection: 15-90 hp, fuel-efficient four-stroke engine or electric motor. 

• Main factors: Stable operation, good range, fuel efficiency. 

Example: If you are sailing close to the coast and fishing, a Mercury 60 FourStroke or ePropulsion Navy 6.0 Evo solid choices because they are quiet, economical and robust. 

Offshore & long trips 

• Typical engine selection: 150-300 hp, four-stroke engines or twin-engine setup. 

• Main factors: Great range, high reliability, power to handle waves. 

Example: A Mercury Verado 250 hp are perfect choices for an offshore RIB, where durability and longevity is crucial. 

What engine size is right for your RIB? 

The engine power must match the weight and length of the boat to ensure optimal performance. 

It is always important to follow the boat's specifications for maximum engine capacity, as an engine that is too large can affect stability and sailing characteristics.

Should you choose a petrol or electric engine?

Technological developments have made electric motors a real alternative, but gasoline engines still have their clear advantages. 

Electric motors are suitable for shorter trips and coastal areas, while gasoline engines remain the best choice for long trips and high speed.

Two-stroke or four-stroke engine?

Mercury produces both two- and four-stroke engines, but two-stroke engines are only for commercial use. Four-stroke engines are more efficient and environmentally friendly than the older two-stroke models. 

Advantages of Mercury four-stroke engines 

• Better fuel economy 

• Less noise and vibration 

• Longer lifespan and lower emissions 

Two-stroke engines are still found on older RIB boats, but they are being phased out in favor of more efficient four-stroke models. 

Maintenance and lifespan

The engine's lifespan depends on proper maintenance. 

• Rinse the engine with fresh water after use in salt water. 

• Change oil, spark plugs and filters according to manufacturer recommendations. 

• Use a fuel stabilizer for long-term storage. 

• Check the gear oil and impeller regularly. 

Mercury's four-stroke engines are known for their durability, and with regular service, an engine can last for many years without major problems. 

So which engine is right for you? 

• Do you sail short trips or use your RIB as a tender? Torqeedo or Temo. 

• Do you use your RIB for water sports? Mercury 115 Pro XS or 150 FourStroke. 

• Do you fish or sail longer distances? Mercury 60 FourStroke or ePropulsion Navy 6.0 Evo. 

• Do you sail offshore? Mercury Verado 250 or twin Mercury 300 V8. 

The right engine depends on your needs, the size of the boat and your priorities between power, fuel economy and maintenance.
