I had my 1977 bonanza out yesterday. It was going good. When we stopped and killed the engine. We fired it back up and we tried to go forward it wouldnt go into gear. Sounded like it was still in neutral. When i tried going into reverse gear it worked. Do these have a fuse for them. Or what could the problem be. Thank yous for all of your help. I am very new to this boating scene. Rocky start i replaced the lower unit already. Wandering if it could be the forward coil or the switch.
