Motor not running in neutral hand spin the prop, free spins about 1/4 turn then sounds like it hits something has a clanging noise. does this in both directions at about 1/4 turn is this a big problem, just play or normal ?? once at 1/4 turn i can still freely spin prop just sounds as if it has slop till the 1/4 turn mark.. When motor is running rev motor and it rattles loudly like a bad bering from prop shaft area... what is this ??? PLEASE HELP
