444 CPMY gennie exhaust & port list

Postby Foster15 » September 17th, 2017, 10:39 am

Morning from Racine. I have a 10 kw gennie with under water exhaust. It also has above water line port aft quarter exhaust outlet. No water comes out of the above water outlet. Is this normal? No evidence of overheating and exhaust is not hot to feel.

Also have about 3 inch port list. Any thoughts on reason or fix?

Chances are you have an exhaust/water separator. This diverts the cooling water below the water line and the gases/exhaust above. This helps to quiet the belching you usually hear with regular above water exhaust systems.
Here's an example of one:

As stated above the 444 has a diverted genny exhaust muffler with the water going out the bottom of the hull and the exhaust out the back. As far as the list goes, I believe you have 4 fuel tanks on that model. Two 122 gallon saddle tanks amidships and two 80 gallon port and starboard tanks in the stern. Is it possible the fuel is not evenly loaded? The holding tanks are 36 gallons each and they too are situated port and starboard (not cross connected) so if you are using the master more it is located to the port.
