The latest in a series of new-generation compact diesels from Yanmar Marine is its three-cylinder 3YM20, developing 21HP (15.3kW) at 3,600 rpm. Displacement is 0.854 litres. The naturally aspirated 3YM20 features a completely redesigned cylinder block and combustion system, configured for quietest possible, vibration-free running. It is a vertical four-stroke, fresh water cooled. With indirect injection and a swirl pre-combustion chamber, this all-new unit complies with EPA Tier 2 and BSO/SAV Stage 2 emissions regulations. A compact control panel, injection pump, electric stop solenoid and 60-amp alternator are introduced as standard. To meet heavier electrical demands, an 80-amp alternator is offered as an option. Maintenance has been simplified, with the water pump, fuel filter, oil change and dip stick located on the same side of the engine, at the front.
