Hey everyone. I've got a pair of 2008 BF225s on my Everglades. I had an issue with the port motor burning oil. While on the river coming in, I noticed it had alot of oil dripping down the side of the cowls making a nasty mess in the water. Great. I figured I had blown a head gasket. While disassembling, I noticed it had alot of water and oil mix in the left side of the engine (if you are standing behind the boat) so I popped the head off, had it surfaced, new Felpro head gasket, torqued, Yay! It ran great on the hose in the yard. Put it in the water and it pumped the block full of water. I took it home, took the head off and put a Honda head gasket in and new Honda head bolts. Put it back together, run it on the hose, runs great, so I take it back to the river and put it in. I run it for ten minutes and it fills the engine with water again. There is no water in the combustion chambers but it is pushing oily sludge out of the exhaust in the prop. Any guesses? I'm thinking maybe a cracked head at this point. But, my BF225s both have ZY3-1-HF cast onto the head. Is that the head part number? I've searched for that and can't find any heads by that part number.
