Yanmar Marine has recently introduced its all-new 3JH5E diesel for sailboats and motor craft, also available in double-seal saildrive configuration. Replacing the 3JH4E. tHE 3JH4E it is based on is a completely redesigned cylinder block and new combustion system, developing 39HP (28.7kW) at 3,000 rpm.
This is a naturally aspirated three-cylinder diesel, producing 25% more torque than the model it replaces from less than 10% increased displacement, now at 1.642 litres. A modified intake silencer, low vibration and decreased operating rpm contribute to an average reduction of five decibels in noise. The 3JH4 runs cleaner and produces less smoke, complying with EPA Tier 2 and BSO/SAV Stage 2 regulations.
For easy maintenance, a gear-driven sea water pump is mounted at the front of the engine, close to the fuel filter, oil change and dipstick. A new-design V-pulley ensures long belt life. An electric stop solenoid is standard and a new compact control panel is available, complete with hour gauge. As standard, the alternator is 60 amps and an 80 amp option is offered.
The engine is the same size overall as its predecessor, with an identical footprint, allowing for ease of installation or repowering.
There is a choice of mechanical transmissions, or the heavy-duty SD50 saildrive.
