I overheated a 1997 Volvo Penta 4.3gi. Following this the motor would not start. After inspection I pulled all the plugs out and the #5 and #3 cylinders had sea water in them. I don't know if this is from a blown head gasket or cracked block. Is the engine ruined either way? What steps would you take with the mechanic? Water pressure test? Thanks Jeff

Take the heads to a local head shop and check for warpage. The 4.3L (GM block) has a 0.002 max spec. And they warp when overheated. If they are warped, just have the guy surface them and reinstall.

How hot did it get?
Unless it reached melt-down point, you're probably looking at head gaskets, and maybe a warped head.
