Given the corrosion properties of Salt water on engines, are there any "closed circuit" cooling systems available for the 190hp V6 found in the 185? I have heard of "heat exchangers", but I am not really sure if this is what one would use. The purpose is to remove the need to have salt water circulate through the motor.
A more general question; Why don't boats just have a radiator like a car rather than circulating corrosive salt water through the motor?
