The first of Yanmar Marine's new-generation compact diesels for sailboats and runabouts, the 29HP (21.3kW) 3YM30 inboard and 3YM30C double-seal saildrive version, have gone into full production. Based on a completely redesigned cylinder block and combustion system, the new engines are quieter, produce more torque and run cleaner than the models they replace.

They comply with the latest stringent EPA Tier 2 emissions regulations. Naturally aspirated, these latest Yanmars have an extra 12% displacement, now at 1.116 litres, rated 29HP at 3,600 rpm. The flat torque curve from 3,200 rpm upwards allows a choice of propeller size, matching the prop to the application.

For ease of installation in new boats and for repowering, they are the same size as their predecessors and have identical footprints. A new compact control panel, injection pump, electric stop solenoid and 60-amp alternator are introduced as standard. To meet heavier demands, an 80-amp alternator is now offered as an option.

Maintenance is simplified, with the sea water pump, fuel filter, oil change and dip stick located on the same side of the engine, at the front. The 3YM30 has a servo-cone clutch with a choice of 2.21:1, 2.62:1 and 3.22:1 forward ratios, plus 3.06:1 in reverse. The 3YM30C saildrive version has a dog clutch, geared at 2.64:1 forward and reverse.
