O:P),

Of course you can, BUT:

1. If it is run at its sutomotive rating it will probably fry. Passcar
automotive ratings are most often peak ratings that do not reflect the
long term capability due to internal heat buildup.

2. Without air flow around the engine lots of stuff can get cooked -
ignition wires, valve gear cover gaskets and other things that I don't
remember right off.

3. Like with the above, the oil will not be cooled by the dwell time in
the oil sump, so an oil cooler will probably be required even with
derating to marine output.

4. If you try to run it with raw water cooling, the passcar headgaskets
will probably last about a week because they corrode and the coolant
flow pattern will change. This is unit specific and you will have to do
your own research.

This does not include changes required to meet USCG regulations.
