1/1

These Special Series engines are specifically designed around the Small Block and Big Block V8 Chevrolet engines and provide significant performance, reliability and efficiency improvements over their standard manufacturers counterpart.

 

Crucially we have designed our engines specifically for marine use, delivering vastly increased torque several hundred RPM lower down the rev range.

 

Once combined with the correct pitch propeller, this results in a faster boat at lower RPM, consequently it will therefore consume less fuel at any given cruise speed.
