Two new engines which are light in weight, small in size and have high-power outputs. These engines contain many high-performance features sure to appeal to the serious motorboater. The overhead cam design develops max hp at higher revs, allowing smaller, smoother running propellers.
Camshaft is belt-driven, reducing weight, number of parts, gear wear and noise.
The STE model even features 4 valves per cylinder for enhanced breathing and top-end performance. And burn efficiency has been improved as well. Reduced Vibration and Noise Two-stage springs in fuel injectors reduce injection noise. And of course belt drive makes for big cuts in timing gear noise, while the 12 balance weight crankshaft and rubber engine mounts soak up much of the usual diesel vibration. The aim is to go faster on less fuel, while at the same time keeping a far better eye on all those vital engine health functions.
