Question about marine diesels
Funny you ask. I actually have a VW Diesel truck engine in my boat that has been motified for the marine environment. The main differences between a marine diesel and a automotive type diesel are the cooling system and the transmission. It would certainly be valuable to learn how to work on automotive diesels as this knowledge could easily be transfered to the marine environment. As mentioned previously, there are issues with things such as fuel quality, raw water cooling systems, and marine DC systems that you would need to learn at a later time. Of course, if you are willing to travel, several marine engine distributors like Mac Boring (not such of the spelling) offer courses. Good Luck.
