I need advice on how to get the midsection on a 1978 Evinrude 35HP off. I have a worn out rubber grommet atop the water line and it's not pumping water out of the tell tale. I replaced the impeller and water pump. Blew air through the line. Also, began to take off screws to attempt to drop the midsection. I have all screws out that I can see but I do not know if there is a hidden screw somewhere that is keeping it attached to the powerhead. My manuals for Johnson/Evinrude only go to 1970. Any help would be appreciated.
