Advantages of QSL8.9 Marine Engine

1. The integration design of cylinder block and cylinder head prevents the engine from water and oil leakage. The parts are about 40% less than engines of the same type, and the failure rate is greatly reduced.

2. Advanced design and high-quality manufacturing, adaptable to severe operating conditions, high strength, and reliable operation under heavy load.

3. The three-stage filter ensures balanced particle dispersion, protects main components of the fuel system and maximizes engine life.

4. Holset supercharger with integral wastegate offers low-speed response and dynamic performance.
