new to boating so any and all help is greatly appreciated, while winterizing outboard, 80hp mariner 1980, ran gas out until stopped while doing that a garbage bag got pulled by prop and wrapped around shaft and stalled engine, removed bag and restarted engine, prop would not spin, thought there would be a shear pin to replace but do not see anywhere that could be, maybe a slip clutch i thought but dont know, anymore info needed please let me know trying to do this myself which im sure is feasible just dont have any info, thanks in advance mike
