OK, here's what I have. A friend of mine called and asked me to fix his boat. I asked what was wrong and he said that when he puts the muffs on it and runs it, looks like water leaks from a freeze plug on the engine somewhere. First of all this is a Mercruise and he thinks it's a 140 or 150 hp, 4 cylinder. And second, now you all know what I do about this fix. Well..........should I go ahead and mess with it or is there something someone knows that I should. Like it's a nightmare, don't get involved, I've heard of this before, I know what it is etc. So if you can help, know what it might be, please let me know. Sure does seem like my friend doesn't even know what he has. Just said, ohhhhhhhhhhhhhit's a Mercruiser, believe 140, 150 something 4 cylinder.<br />Bottom line is, he needs help, came to me and I'm gonna do what I can to get'em goin.
