Started her up on muffs in the driveway. Shifts forward, reverse, very easy. Out on the water, put it in reverse to back away from the ramp. goes into forward just fine. drive around, engine is working great. When I stop I put the shifter in neutral and the engine idles but won't disengage. It shifts very hard into reverse, and once in reverse, shifts into neutral just fine. The into forward just fine. What's up? Am I looking at the dreaded shifter cable change?
