Hi everyone,
I rebuilt this Mercruiser 5.7L 350, I don't have the serial number for it since it was originally an automotive motor but all of the accessories, e.i. manifolds, carb, dist came off a 1979 Mercruiser 5.7L. Anywho, I was running it on the ground after the rebuild, all was going well and running great...then I turned off the motor briefly and when I went to go start it again she was locked up. It basically cranked with a delay, I turned the key to start it, didn't turn and then a few seconds later it cranked in a painful mannor. Pulled all the sparks and sure enough a bunch of water dumped out all the cylinders.
So far I've only pulled the plugs, cracked the motor a dozen or more times, and fogged all the cylinders. Maybe if someone can tell me why this happened and what else I'm gonna have to do to fix it I can avoid this ever happening to me again in the future. My guess is I had the water pressure up to high and when I shut er' down it forced water where it should be but idk. Did I just blow out my head gaskets? Thanks for your help I look forward to hearing what you all have to say.
