If I understand correctly, the M-18, then, is cooled BOTH by fresh water and raw water. Right?

I'll give it a shot.  The M-18 is a 2 cylinder, 14 hp, fresh water cooled engine.  It has a heat exchanger mounted over the transmission and a belt driven fresh water pump.  It has a raw water pump driven straight off the engine.
The 5411 or M-15 is a 2 cylinder, 11 hp, raw water cooled engine.  No heat exchanger or belt driven water pump, but it does have a direct drive water pump.
My M-18 has a data plate on the front stbd side of the valve cover.

Re. Heat Exchanger
 
You are a step ahead of me.  Wanted to make sure I had not missed something on my Model 15 (5411), raw water cooling.  Did not think I had a heat exchanger.  BTW what is the difference in a Model 15 and 18?  Heat exchanger?
