THANKS!! This thing is killing me I've been doing this for a long time. I think soemwhere there is a bulletin that talks about the exhaust valves sucking up into the head I think that is what is wrong because it is leaking 20%m out the exhaust
20 % lost is ok...
If you think it's exhaust, do this take exhaust bellows off at horns.... Run engine, you will get water and exhaust in boat...But this will till you if you have exhaust leak
