SeaPiper Engine Choices
SeaPiper is offering two engines: The Betamarine BETA 85 and the Yanmar 4JH110.
The standard SeaPiper engine will be the Betamarine BETA 85. This new engine is based on the modern Kubota engine family and shares most of the core components and technology with these engines. Betamarine has a long history of marinizing Kubota engines and their engine power packages have an superb reputation for high reliability. Beta engines have been used for a long time in sailboat repowering worldwide.
The beauty of this engine is the unparalleled simplicity: there are no engine electronics at all. The engineers have been able to meet EPA Tier III requirements without the use of complex electronics: the BETA 85 is a 2800rpm direct injection diesel with turbo, heat exchanger, a mechanical line pump and a relatively heavy flywheel. As long as there is fuel this diesel engine will run, offering smooth operation and tremendous ease of maintenance. SeaPiper will offer about 10 knots of speed with this 85 hp engine.
We also offer SeaPiper with the new Yanmar 4JH110. This engine is a modern electronically controlled common rail diesel engine with rotary injection pump. Its engine block is completely aluminum and engine RPM is higher at 3200rpm with a power output of 110 hp, meeting EPA Tier III requirements. Yanmar has a long standing reputation offering highly reliable engine packages. The 4JH110 is incredibly smooth and quiet and will give SeaPiper a speed around 11 knots.
Both engines are equally good choices for SeaPiper, with a different usage in mind: for maximizing range, economy and ease of maintenance the Beta 85 will be a great choice. For maximizing speed, and silky smooth car engine like running the Yanmar 4JH110 comes out as an equally great choice.
