I got a new starter drive unit for my Mercury with the Merc-o-matic and I twisted it out not knowing it that I wasn't supposed to do that. Do you guys know a way to retract it? I saw a video using a wire wheel on a bench grinder to spin it up and rewind it, but I don't have a wire wheel for mine. Can I spin it with the starter out side of the car and force a retract?
