I was going out for a day out boating for the first time this season. After unloading the boat and taking it to the dock, I noticed that the water pump was pumping out a good amount of water. Did not think of it much at first. I drove the boat out a little and noticed the water pump still pumping out water!! I opened the engine cover and noticed that it was full of water!! I drove the boat back to the dock and loaded the boat back on the trailer. I opened the drain **** and let all the water drain out. Checked for any holes or cracks around the outdruive and lower body of the boat and found nothing. I backed the boat back into the water and watched the engine compartment for any leaks. Nothing. I started up the motor and saw water coming out near the engine head behind the power stearing pump. There is a good size hole there but not an hole from a breakage or anything of that sort. Looks like a freeze plug hole. Could the winter have popped out a freeze plug? Lets me know what you think. Thanks!
