Does anybody know who makes the base engine for westerbeke, my previous sailboat had a universal m18 which is actually a Kubota tractor engine modified for marine.
Looking to try and find westerbeake parts cheaper.

Pretty sure it is a Mitsubishi base engine. I don’t know which, but with some investigation using the displacement and bore and stroke info, you can get to the particulars.

Most are Mitsubishi but some larger models are Isuzu. Westerbeke however has a contractual agreement with both engine makers and no dealer of Mitusbishi or Isuzu engines is allowed to sell components for a Westerbeke engine.
