We had a freeze plug do it's job. This was on a 4-cyl MerCruiser I/O
block, 1980's vintage, which I THINK was just a reworked GM Iron Duke
motor. Boat was out of the water for the season, but we got a sudden
freeze before we could flush the jacket. One freeze plug came all the way
out, another came part way out. No cracks in the block.
