I have a 1963 75HP Johnson Seahorse with electric shift. Having a shifting problem. Operates fine in reverse. Neutral does not work. When shifted into forward it hits hard and the engine dies. Tested wires going into lower unit and voltage is correct. I have taken the prop shaft and gears out. I noticed that the spring on the reverse gear will only move freely in one direction and the forward gear will move in both directions. Is the forward gear spring broke? I did have a major leak and the unit filled with clear water (no oil). I also discovered a bare wire to the electric shift, just above the prop shaft housing. All bearings seem to be ok. Is one of the springs broke and where can i find parts. Please Help!!
