I have a 1975 Crestliner muskie 550 with a 1982 johnson 70 hp, and the starter gear engaged the flywheel while it was at full throttle. Has anyone experienced this before?
Was the spring on the bendix assembly ?----Have you check for a faulty ignition key ?-----Was any work done on the wiring recently ?-----Are you sure it engaged at full throttle or it never came down after starting ?
Taking a wild guess without counting the gear teeth, if the motor was running 5500 RPM, the starter would have to turn something like 50,000 RPM. Ain't going to happen.
