ok all i was diging in older posts and i found one the sounded like my problem, come too find out it wasnt the shear pin it was the rubber incert on the prop that had spun, this will act like a shear pin or a slipping of the clutch..........

i would still like too say thank u for all your help and too let everyone know that this site rocks



yours truley

a happy boater

Re: 9.9 johnson sher pin problem

Has to be the prop hub slipping as your motor doesn't have a shear pin - proshaft is splined. Easiest way to confirm is to take a Sharpie and mark the propshaft and the propeller with a line, run the motor, and then note if the lines are still aligned...
