I had the same problem 2 years ago. I had trouble getting it to turn over. Pulled the plugs and here comes the water. Mine ended up being a cracked cylinder. I sleeved it and made it through the summer. I replaced the block that winter.

Compression may be higher due to the water in the cylinder. You need to do a leakdown test, or put pressure on the cylinder and see if it pushes water out the outdrive or exhaust.


TeamBaja and THRILLSEEKER, what part of Ohio are you from and which Islands are you talking about?

Thanks
Brian

We figured the pressure was higher from the water in the cylinder.

Im from Bucyrus, which is in between the lake and Columbus. About an hour each direction. We go to Kellys island the most, and Put In Bay.......

My guess is that it's painted the wrong color. If it ain't black it's just a grenade waiting for the pin to be pulled,,,,,,,,,,,,

So Im guessing you voted "other". Unfortunately, everything on that motor is black so I'll have to rule that out. Otherwise, Id run to the dollar store and get a case of Black paint if that would solve my problem..........

We tore it down to the block tonight. There is a bad spot on the head gasket on the problem cylinder.

The guy I bought the boat from told me it had a crate motor just installed about 2 yrs ago. The block looks good, but the heads have been shaved down alot and looked bad. I officially declared them as anchors. Ironically, my dad had a set of heads he had completely redone (Im working on it at his house!). They were identical, same #s and all! They look brand new, so tomorrow will be a day of serious gasket cleaning, and misc part cleaning.

Also, did you know you could order a Dominos pizza, then tear down half the engine and take a long break before your pizza arrives?

Pizza, Coca Cola, some orange slices and Oreos. That's the ticket to engine work.

Just curious if you checked your exhaust? A little water in the cylinder can cause a head gasket to blow real quick. It would be a shame if you put it all back together only to find the root cause was a cracked exhaust as suggested earlier.
