Ray, the machine shop took a look and just too much corrosion to save them and get a good seal. Sort what I expected, the pictures unfortunately don't do it justice how bad it looks. I'm getting some reman heads and a lot of my components, valves, etc looked really good so some will be reused. Bill,...

Hey Ray, I should have posted this pic along with the other . Does show some surface pitting on the #7 cylinder wall. Mechanic and another friend said may be OK, just never know.

Not sure if these will show much...

He just said there was NOT water in the cylinders when he pulled the heads, but evidence of "old damage" specifically scarring in one cylinder ...

Probably not with my limited experience and time Scot. I have a feeling I should have it done right and not try and tackle a rebuild myself.

Been a long time reader of this forum and a few months ago just bought a new to me Bertram 28 with Mercruiser 350's. Long story short, Port motor had what I thought was an exhaust leak, but now looks much worse. When the mechanic pulled the manifolds off they were corroded and worse so we're where t...
