You can pretty much make any engine work. Heat is the biggest problem.
Even
though the block may be water cooled, you'll still need to get airflow to
the radiator. Exhaust heat will be a big problem and could become a hazard
if the engine is enclosed. Check out www.surpluscenter.com for misc gears
and parts.

The "raditaor" is called a Heat Exchanger (in a boat) and is cooled by
seawater not air.
