Yanmar Releases New 30MHP Engine and New SD25 Saildrive

Two new Yanmar products specifically designed for the yachting fraternity have been released in Australia with immediate availability. The new Yanmar 3YM30AE marine diesel engine plus the Yanmar SD25 Saildrive provide the perfect power solution for mono hull yachts and cruising catamarans.


The Yanmar 3YM30AE complies with the current USA EPA Tier 3 emissions regulations and supersedes the highly successful and market leading Yanmar 3YM30 model.

Despite having the same outline, dimensions and footprint, the new model Yanmar has a range of significant enhancements. The Yanmar 3YM30AE generates more torque, features a bigger displacement 3 cylinder block, (1.266 litres versus 1.115 litres), a bigger output 125 amp alternator and new belt system. All of these benefits are delivered with a weight gain of a miserly 4 kgs.


In terms of performance the new model Yanmar 3YM30AE is a sure winner. Power output has been beefed up to 29.1 mhp at 3200 rpm. The maximum rated speed of the new model has been reduced to 3200 rpm compared to the 3600 rpm of the superseded 3YM30 model. As a result of the reduced maximum rpm & new cylinder block design, the noise and emission levels have been reduced and the engine torque increased.


“The release of the new Yanmar 3YM30AE projects a telling message from Yanmar to the boating market,” said Michael Blair, National Marine Sales Manager – Australia for Power Equipment.


“Yanmar has taken a market leading model and reengineered it to make it even better. Significant changes have been incorporated into the new model giving real benefits to lower emissions and enhanced performance.”


With the installation footprint identical to the superseded Yanmar 3YM30 engine, repowering of older Yanmar powered vessels is easy and quick. The Yanmar 3YM30AE can be supplied with the Yanmar KM2P-1 transmission for shaft drive installations or the new Yanmar SD25 Saildrive unit.


The new Yanmar SD25 Saildrive has exactly the same outline and dimensions as the well proven and highly durable SD20 Saildrive. The new model is identified by a light grey, non-metallic paint on the leg, while the head remains Yanmar grey metallic. A hard anodizing process is applied to the SD25 to deliver a significant increase in corrosion resistance.


The Yanmar Saildrive SD25 is purpose matched to Yanmar’s 1GM10C, 2YM15C, 3YM20C and 3YM30AE purpose built marine diesel engines.
