The previous owners of my Catalina 30 had backflowed the exhaust water into the cylinders and destroyed the A4 that way.
I bought a rebuilt A4 and installed it and finally have had the chance to use the boat a bunch the last couple of months. I found that I was having issues with my RPMs only going up to about 1300 and after I wasn't even able to fight a breeze to get out of my slip I decided it was finally a problem.
I found water in the oil once again. I have religiously closed the seacock when cranking and really don't know how the water got in there. Perhaps it is just because of the small amount of clearance from where the raw "used" water enters my hot section of the exhaust? With the Catalina 30 there's really no space to put it any higher.
Anyone have any suggestions?
One thing I was thinking was to install the closed fresh water system but the fresh water cooling system that moyer sells would not fit either as there is no clearance behind the flywheel for the 2" required.
I had also changed out the entire exhaust hose portion of the exhaust but it still has the old muffler. Is there something in the muffler itself that could be backing the water up?
