I am going to see a boat this weekend that has an old, 1975, diesel engine - Westerbeke 4-91 with 3200h on it. It appears to be in good condition and I think it had a good maintenance and some upgrades over the years. Since I am new to diesel engines I would like to know your opinion on the Westerbeke as the engines themselves, parts availability (letís say in Caribbean and South America) and also on the age of this particular one. 3200h sound a lot but is it for diesels? I canít say anything about compression or how it cranks since I did not have chance yet to see it.
