I have a 200 hp johnson with a shifting problem while it is on the trailer I can crank the motor and put it into foward and reverse and back into neutral without any problem with the water hooked to the foot but as soon as I put it into the lake and put it into foward or reverse it will not let me shift it back into neutral. I can stop the motor from running and it will let me shift it back to neutral but only if the motor is not running has anyone seen this before?
