Several types of U-form diesel engine have been historically produced, by companies such as Lister Blackstone and Sulzer Brothers Ltd. The main factor and most over looked cause for shortened engine life is engine load, mostly caused by oversized props. A half gallon of gasoline carried on board to fuel the dinghy motor turns a diesel boat into a gasoline boat. A new clean system under moderate load should operate at the lower end of this range and a dirty system under full load might operate in the upper range. Main engines have rotating vanes fitted to them instead of Rotocap to help them rotate. Unlike gasoline engines, diesels need to be under load to reach optimum operating temperature—if they’re not, unburned fuel can cause needless pollution and even can dilute the lubricating oil, increasing wear. Diagnose and fix marine diesel engine problems at sea.
