I have a 1973 model 9.8 hp Merc that has performed well for me up until I just broke it our of winter storage to discover that I could not shift it out of forward gear. It starts and runs well but I can not shift it into neutral or reverse gear. I am afraid if I put too much pressure on the shift handle that I will bust it off. <br />I would appreciate any assistance in solving my delimna. Thank You
