Hello! I have a Westerbeke
33, built between 81 and 83.
My experience and research
tells me that original Westerbeke parts
are very expensive and, in most cases, a rebuild would cost between half and 3/4 of the price
of a new engine.
I have shelled out some cash on maintaining the cooling
system (water pump, exhaust
manifold, heat exchanger) and some other tid bits, but I'll never rebuild her. I'll spend $12k on a new engine before $6k on a rebuild kit from Westerbeke. Personnel preference.
Remember that Westerbeke only marine-ized the engines. If you can find the original maker of the block, you could, in theory, rebuild it for much, much cheaper. But that is no easy task. I have gotten close to finding the maker of my W-33, but can't find the parts online. And not many tractor shops in NYC
to ask for assistance.
On your question about a replacement, Google
around for people with your boat and that have replaced. Appears the Kabuta / Beta have near direct replacements
for my W-33.
