OVERHEATED, NOW WATER IN CYLNDERS???

[boatman1959]

I HAVE A CHEVY 305 1977 IN THE BAYLINER THAT IT CAME IN. THE IMPELLER FAILED LAST WEEK AND IT GOT HOT. I PUT NEW ONE IN AND LET IT RUN FOR ABOUT 2 HRS AND ALL LOOKED FINE. I WENT TO GO OUT THE NEXT DAY AND IT WARMED UP, RAN AT 160% AND WHEN I WENT TO PULL OUT OF THE SLIP I GOT ABOUT 50 FEET AND IT DIED AND WOULD NOT CRANK. I PULLED THE PLUGS AND FOUND CYLNDERS FULL OF WATER ON BOTH SIDES. IT IS NOT FILLONG THE OIL PAN W/ WATER BUT WHAT DO I START LOOKING FOR????????

The heat probably cracked your exhaust manifolds. You'll have to take them off to see for sure. Don't kick yourself too hard though as they were probably about due for repacement anyways. If your engine is FWC thats about the only place for water to get in.
