This outstanding eight cylinder 13.93 litre engine offers the greatest degree of efficiency, durability and refinement.
The specific fuel consumption rate of the engine when directly coupled to the dynamometer is the remarkably low value of 0.329 lb./per b.h.p./hour which represents an overall thermal efficiency of over 40%.
The engine is designed for use with a fresh water closed circuit heat exchanger or keel cooler system. Coolant is circulated at high rate by a centrifugal pump and temperature is automatically controlled at all loads and speeds from idle to maximum output. The novel exhaust system, which secures avoidance of interference of one cylinder to another, is conveniently arranged upward pointing with the inlet manifold located below it.

There is an ever-increasing demand for higher speed, improved handling, enhanced onboard comfort and reduced emissions.
Buyers of sports cruisers, sport fishing, flybridge yachts and other craft with traditional inboard propulsion want speeds well above 30 knots. But this is where the efficiency of conventional shaft installations really starts to drop. Something new is required to combine performance with driving pleasure, onboard comfort and reliability with good environmental properties.
