Well, I did forget the drainplug, but to make matters worse, that is attached to the oil drain tube, so the prop chopped off the end of the drain tube, and the motor sucked up a lot of water. The boat ran fine, had good oil (water
) pressure, and I got no alarms. I've changed the oil 4 times, with a new filer each time, and I'm still getting milky oil out. It's getting better, but slowly. Is there a better way to flush water out of the system?
