Engine Re-Power CSY37
« on: June 10, 2019, 03:51:58 PM »
Looking for recommendations, experience in re-powering a CSY 37.  My current engine is a Westerbeke 4107 40 HP - original engine.  So far looking at Volvo 50 HP and Yanmar 45 HP and 57 HP.

Any suggestions would be appreciated.

Thanks...Peter

Hi Peter,
Have you checked out Beta Marine diesels?  Altho I have no direct experience with them, the folks on Cruisers Forum have nothing but good  things to say about them.  Based on Kubota blocks, and the parts should be cheaper than Volvo or Yanmar. Beta makes engines in the power range you are looking for.
If I was replacing an engine, some of my main concerns would be that the engine could be an easy replacement for your W40  with few modifications to the stringers, angle, etc., naturally aspirated so you don't need to do turbo maintenance, and if you can match up your existing tranny to the new engine would be a plus because if the reduction gear is different, you may need to change your prop, too.
