I have a 1988 Force 50hp ser. 507Y8C. Im haveing trouble removing the powerhead to replace a blown gasket that is between the powerhead and spacer plate. I have the 5 bolts out from the top and the 2 bolts out from the bottom front. the powerhead can wiggle a small amout side to side, but wont lift off...The lower leg is off so I know the powerhead isnt stuck on the driveshaft. All linkages and wireing have been disconected also. Any Suggestions?
