I've read all the posts concerning the water jacket issues about water leaking around plugs, but just can't seem to find any gasket or part labeled "water jacket" for my motor, so here we go.<br /><br />I have a '72 Merc 650 and I put a water pump kit on (it wasn't peeing before). With the new impeller, it MUST be moving water cuz it it squirting out around the two bottom spark plugs. I had replaced the gaskets in that area, but I did not put any "liquid" gasket w/it, which apparently is what everyone does. Anyway, I cannot find anything that refers to a "water jacket" for this motor. <br /><br />Also, I see where you all have talked about sealing around the plugs themselves. Not sure what you are talking about exactly. Anyone got a diagram? 
<br /><br />Had a "part-time" boat mechanic tell me my motor was fried, that's why water is coming from plugs, since I had replaced the gaskets. I think he just wants me to sell it to him....cheap.<br /><br />Is there something catastrophic that could be wrong to cause this issue? It didn't start until after the new pump parts, but then again, the old impeller was totally gone so who knows if it would have happened before. Thanks once again, for all your help!
