i have just swaped a 50 hp 77 evinrude with a 85 hp 77 evinrude everything lined up. but when we hooked up the perviously working controls it would not go into forward. so we took the controls and cables off the donor boat and put it on the bass boat. the controls again worked fine when mounted but when hooked up to the motor no reverse or neutral and we took the cables back off the motor no reverse and neutral whats the deal here thanks
