OK, what did I do. last time out motor ran great, no issues. Today I go for a cruize from Viera's to Wimpy's for lunch. Glass smooth water. About two miles and the motor starts sounding rough, I back off the throttle and gets worse, about the time I'm reaching to shut her down, she dies. Did not sound good at shut off. Did not try to restart or turn over. Looked like I had a lot of blowby. Has vacuum pump and breather is pumping out milkshake. Pulled the oil dipsick and water starts pouring out. Motor is completly full of water, all they way up to the vavle covers.
Any ideas to look for when I tear it down?
