Hey guys, I just bought this boat a month or so ago with hopes of taking it out a couple more times before I HAVE to winterize it. I have yet to buy a repair manual ( on my list to do) but I have searched vastly on here have yet to find similar thread to my motor. I have a 1990 Force 50 hp model number 507X90D. I read on forces of a small allen head bolt for the drain etc... mine has nothing of the sort. The bolt at the lowest point says fill and the top says vent. I would assume the lower bolt is the drain and the top is to allow the flow to drain quicker, but fill from where and how much. I was expecting more along the lines of a rear diff on a truck as in drain and fill where you fill it to where it begins to seep out. any help much appreciated.
