We have a Cabo Rico here in the UK, fitted with a Westerbeke 52 engine. I noted that at least one of you had this model, and mentioned that non-marine parts were available, so I was wondering if you know on which engine it is based? At the moment ours is running perfectly, but you never know.
If anyone does have any information I would be most grateful to hear from you.
After a lot of time spent online and mucking about in bookstores that sell shop manuals, I have come to the conclusion that the Mazda R2/S2 diesel found in early '80s B2200 and Ford Ranger pickups is the same engine (minus heat exchanger and water pump) as not only the Westerbeke W-52 but also the Perkins 4.135, which wasn't a particularly popular model for Perkins.
Rebuild kits for Mazda B2200 engines exist as they were very popular in Australia and, being light-duty diesels in a country largely without rain or snow, a 25 year old pickup is still in many cases in daily use.
Here's a Mazda R2 2.2L diesel:
and here's my Westerbeke W-52
I am still sourcing rebuild kits, but I would like to just replace from Westerbeke the specifically marine bits.
