I have a 1991 90hp Force w/L-drive.I'm trying to remover the lower gearcase to replace the water pump impeller. I've removed the exhaust snout and the seven bolts on the lower unit. disconnected the shift linkage. the lower unit will drop aprox 1/2 inch but won't come off. did I miss something? or i'm I to beat it off with a hammer? is there some other pin or something I missed?
