Diesel academics

I am interested in buying a catamaran which will probably have twin diesels. I would like to take a course on Diesel engines/repair before I buy it.

Are marine diesels different than diesels in trucks/heavy equipment? Do I need to take a specialized course with marine diesels?

Thanks.

Same same. The only real difference is the "radiator"

Thanks...any difference in makes/models or is a basic course gonna pretty much cover what I would need to make many repairs myself.

I see Yanmar is pretty popular but don't know of any other brand names.

Re: Diesel academics

Beta, westerbeke, perkins, yanmar, nanni, caterpilar, cummins etc. Just learn the basics well and you'll be good to go. Most diesels problems seem to be fuel related... either air or gunk in the fuel.

Re: Diesel academics

Marine diesel engines are usually tractor engines with a heat exchanger and impellor added to cool the engine using sea water.

Volvo Penta = Perkins
Beta = Kubota

To simplify and diagnose a problem on a diesel engine you need to break it down to three things.
Diesels engines need only 3 things to run. If you are missing any one of these it will not start.
1) Air
2) Fuel
3) Compression

A basic course will cover all makes, they all work the same with a few exceptions that you'll never see on a small boat.

Re: Diesel academics

The engines themselves are identical. However, the peripheral components particularly the cooling system is different.

It tends to be the peripheral components that fail in a marine environment.

Any experience, or course, on deisel engines will be beneficial, but if can find something targeting marine deisel engines it would be better.
