Industrial engine ,, marinization question

As most of you know, the Beta marine engines are Kubota. The Universal
engines are Kubota, as well.

After a visit to the boat show, and looking at the Beta small diesel for a
sailboat, I was flabbergasted
at the price. I got home and decided to see what the base engine cost.

For the Kubota [ Beta ] the price was less than half of the Beta price.

Huum,, I got to thinking..

Take engine, add transmission, heat exchanger, a couple of pumps..

If you know anything about a DIY Marinization .. ??

This would be a Kubota .. I'm thinking about 15hp.

2cyl,, fresh water cooled.

Well Sir Thomas,

This is a road I personally have traveled many times. First by self and
then with so many others.

The engine is about half the cost - True.
For that you get an engine on the floor on a wood skid.

You need to add at least:
- A marine transmission that will probably require a bell housing and
drive plate specifically adapted to that flywheel.
- A heat exchanger, raw water pump and a system head/expansion tank
(with brackets).
- A jacketed exhaust manifold a isolation elbow to create a wet exhaust.
- A marine air intake system (many times the stock will work on a diesel).
- A set of mount brackets acceptable for a marine mounting application.
(you will have to look at the engine and transmission prints for a
where to start).
- A remote engine control harness.

You might want add an instrument package and an upsized alternator.

If you (like I) are a marine engineer and navel architect with lots of
experience, you can probably do the complete adaptation package for 75
~80% for the quoted cost of the packages you looked at at the show.

A company used to sell VW golf/rabbit engines in marine trim for just a
little less than the price of the complete car.

Good luck, but do the research before you commit to buying anything.
