Could be the oil seal? Have you checked the exhaust housing gaskets?

Re: 2000 70 johnson water in bottom cylinder

as oil seal are you saying bottom crank? and the exhaust houseing on this thing is only a plate as i can see it .if you are talking of the big plate on side of power head? but yes they seem to look fine nutin visible.

Yes the bottom of the crank seal,also could be a head gasket issue.

hate to sound fool , does the bottom crank and seal get water near it ? reason i ask looks like it dont but im sure im wrong.. head gasket looked good and had 124 comp on it before i took it off. i now have power head off .crank seal was not milky dont know if that helps

just pulled crank seal water did come out and seal looks to be 2 sizes to big for the grove could this be what i been looking for??? but i dont understand how water gets in the block from that seal.the seal im speaking of is the o ring on the crank seal houseing
