Pumping oil out of the motor through the dip stick doesn't cut it, leaves to much oil in the pan. I'm going to hook a line to an AN fitting in the bung of the pan. Because the back of the motor is hard to get to, I would like to put a bulk head fitting through the transom. Does anyone have an idea on this? On my v-drive I can get to the back and put the hose through the drain plug.
