Marine Engine: motor sailers With its numerous merits, this marine diesel is virtually beyond comparison: Three cylinders and an additional compensation shaft give a standard of running smoothness similarto that of a 6-cy Under power unit. Designed from the very beginning for marine applica- tions, this engine saves space and manent angle of heel of up to 30:. The special combustion chamber design combined with direct fuel Injection gives an optimum combustion process and minimum consumption (only 9.5 ltr/2.1 Imp gals per hour at maximum output),The special mounts developed for sailing boats In particular Incor- porate extra-large silent blocks and allow installation of the engine with a low centre of gravity. Also available with twin-circuit cooling (D 50-2). Special features: • Exceptional smooth running due to compensation shaft • Thermostat-controlled salt water constant operating temperature • Now compact twin-circuit coolim] system of the D50-2 with integrated header tankand heat exchanger to provide optimum corrosion- proofing. Warm water supply Imp gals per operating hour at maximum output • Salt water impeller pump driven directly by engine, noV-belt required • Bosch single-element fuel injection pump with mechanical control and self bleeding, inexpensive • Engine runs perfectly even with • High-output alternator and starter • Optimum corrosion-proofing through threezinc anodesand two-component paintwork • Electrical wiring complying with the strict US Coast Guard regulations, resetable fuses to provide extra safety against overload • Wide range of Instruments • Reversing-type gearbox with various reduction-ratio gears for all • Engine and gearbox prepared by the factory for single-lever remote control of throttle and gear shift • Fuel filter with water separator • Electrical engine cut-off switch The D 50 has a wide range ot excep- tional advantages.
