You could try this. A fan sucking from a long duct inside the hull.
If the hull is steel or aluminum, it would be quite effectively cooled
air from the sea water. The duct plays over the cylinder then exhaust
manifold.

I have actually done this with excellent results.

Basically, I contained the diesel generator in a soundproofed box and sucked
air out of the box. The air inlet sucked air that was first passed over a
large area of the steel hull. The incoming air being specifically directed
at the cylinder head area.

As a finishing touch I installed a fire detector and two heat sensors both
of which can independently cut the engine and fuel in the event of the
compartment overheating.

Hope this helps.
