trying to identify westerbeke engine

[motion30]

my friend has a 41-foot 1983 Pearson. it is powered by a 55 horsepower westerbeke engine. we are trying to identify the base motor. Does anybody know the original manufacturer of this motor? does westerbeke make any of its own base Motors?

If it's a Westerbeke 55 A, B, C, or D, it is probably a Isuzu 4LE1 base engine.

Did a rebuiled on a westerbeke that the long block was manufactured by Mitsubishi

The 55A has a curious history. Originally a Perkins block modified by Mitsubishi then marinized by Westerbeke.

Westerbeke are among the nastiest people in the marine business, They do sneaky things like use a standard Sherwood water pump">raw water pump and modify it to fit their uneccessarily modified mounting bracket so you can no longer use a standard Sherwood, they then quadruple the price of the pump. They go to great lengths to used odd shaped hoses with different diameter ends when a much simpler arrangement could have been used. The 55A lower heat exchanger hose can be bought for $20 at an autoparts store if you are willing to invest the time or you can buy one from Westerbeke for $350.

I believe read on another site Sailnet? more likely a very detailed guide to identify it.

I will try and get pictures. I have a westerbeke generator in my boat... a circulating water pump from westerbeke is $350. I determined what motor it was, it's a Mitsubishi 3 cylinder and was able to buy a circulating water pump off of eBay for $69. exact fit just no red paint
they certainly are proud of their parts
