Speaking from my own experience: Early this year repowered the with standard (Bud recomended) Betamarine 38. The 38 horsepower (very close to 35) is quite sufficient to push her through seas on the bow, with reasonable fuel consumption.

60 HP is quite a large engine for a W32, and although super powerful, I imagine would suck fuel.

What I feel you must check on however, is the availablity of reasonably priced parts and service for a 30+ year old BMW diesal engine. 

Also if you can afford it I would strongly suggest the feathering 3 bladed MaxProp. Great performance in forward and reverse, and almost no water resistance whhile sailing.

Thanks for the advise guys !  I'm still looking for the " right"  motor. Just found out my serial # is WSSK 03660175 Anyone know what my Hull # would be ? 366 or 601.  I think 75 is the year.

Thanks for clearing that up for me Werner. So now how can i find the history of the boat? And am i posting in the right forum to check on my serial # 366 ? I'm new and not sure how this all works.   John

Thanks Jay. It sure would be nice to know if my Westsail 32 has or had a name. It is in Norfolk, Va. I understand it was on the hard for many years. I really do appreciate all the help from you Westsail owners. Thank you all.  John Hedlund
