Original Power

A variety of engines were used. The Perkins 4.108 was very common. Perkins 4.154 was used in later production.  Some Perkins engines marinized by Westerbeke were also used. Later models will find Yanmar engines installed.

Repower Recommendations

The Beta 50 has always worked well with this vessel.  The OI 41 is often limited in propeller diameter to 19.  This also limits the power that can be transmitted to the water in an efficient manner to about 50 hp. With a maximum 2800 operating RPM, the slow turning and smooth running Beta 50 provides the right combination of high torque and low operating speed that works perfectly with a 19 diameter propeller.  

As a naturally aspirated and all mechanical fuel injection engine, this powerful diesel is a trouble free addition to your cruising experience. With no turbocharger heat and noise and no black box computer engine controls, the Beta 50 is a completely mechanical engine that is EPA rated for all applications.     

If your current engine was fit with a Velvet Drive transmission, re-using the original Velvet Drive transmission is economical in many ways. It is very inexpensive to recondition this transmission to like new condition and installation is simplified by using the original mounts that are fit to the side of the transmission case.  The Twin Disc TMC 60 Mechanical gear has also been used in this application.
