New to the forum, my buddy and I have a 1986 classic 50, 45hp mercury which runs good and goes forward with no problem. Reverse does not work at all. The cable from the control console move the shift levers on the engine ok. What is the next thing that we need to check? Any help would be appreciated Thank you. The fishing season for Coho salmon has already started here in Lake Superior and we need to get out on the water
