I have a 1991 Froce 120HP Outboard that is having some reverse issue. When I first shift into reverse the engine just rev's, as if it is not going into gear. The engine works fine in forward gear, and after running in forward if you shift into reverse, it will catch and go into reverse. The clutch dog is brand new, and the gears were inspected and looked in good shape. Linkeage problem maybe?
