Anyone know were the "cooling hole (pee hole)" is located on an old Merc 9.8. I got the motor running, with a new impeller, I've checked all over but I have no exhaust for the hot water to flow. I did notice on top of the block, a plug on the left hand side (looking from the back to the front). what is this for? Is it for the exhaust/cooling water? I have a 7.5 merc and I'm a pro at the impeller on it so I don't think that is my issue. Any help here would be appreciated. Thanks..
