1997 Johnson 200 Ocean Runner ran great the last time the boat was in the water. I moved and the motor was not started for about 4 years. All the fuel was removed went it was first moved. I put in new battery and fuel yesterday and it started but would not go into forward or reverse. I removed the lower unit from the motor. The shift rod will not move up or down. I checked the gear oil. It was a little low but looked and smelt ok. Also only a little fuzz on the top screw magnet. Anyone have ideas on how to fix this?
