Pleasure boat engine : in-board diesel engine 100 - 200 hp (indirect injection, natural aspiration)
8LXB (170 hp @ 1500 rpm)
Gardner Marine Diesels
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.
