Is it possible to convert a marine engine over to a radiator cooling system?

Sure.  Is it cooled by raw water or a heat exchanger?  If heat exchanger, just lose the raw water pump and plumb it directly to a radiator.  If it's raw water cooled, you might want to change ther thermostat to a higher temperature.  Lots of marine engines have 160 degree thermostats to keep salt from precipitating out in the cooling galleries.  Many engines that were not purpose-built for marine use were designed for automotive or genertor/industrial use and will benefit from the higher temperature. 

That's the short answer.  The devil's in the details.

Looks like it has a heat exchanger on it.  Thanks.
