Started my engine on my boat today, and didn't see any water coming out of exhaust. I checked raw water strainer and thru hull, and didn't see an issue. Impeller is changed every year, so didn't feel that could be the cause. I pulled the engine cover and found a very rusted out raw water pump housing. Highly suspect this is my cause. I have a 2004 C36MKII with the M35B. Considering replacing with the Oberdorfer N202M-908. Wondering if anyone else has done this, and if I have the correct part #?
