all right, so I pulled the exhaust bypass cover off along with the inner baffle, and didn’t really find anything that lead me to believe there was water getting in through the exhuast holes in the cylinders. There was some pitting on that inner baffle, but the gaskets didn’t show anything that indicated water getting into that exhaust compartment.
I pulled the lower crank seal, which is now called the crankcase head assembly, and found the seal on the inside of this seems to have failed. So I’m guessing this is where the water was coming in through, or perhaps somehow pressure was stopping water from the pump as per what everyone was talking about. Am I correct in this conclusion?
The water I found in the cylinders was probably from when I ran the motor in the test tank last friday, and what was left over in the crankcase/cylinders. Whatever water I used to pump through the motor today via garden hose probably just went as it should through the cooling system and passed through. I haven’t found any blockages in the water system; the thermostat was pretty well clogged up with debris and the overboard "L" was plugged nearly solid with some small pebbles. This is probably why I could barely get water through the cooling system with the garden hose today.
