[QUOTE="old_fart, post: 488193, member: 28990"] Had more than one instance where a bad hub felt just like a bad clutch dog. And, as best I remember, it was on 40HP and less (this being the days before thru-hub exhaust). Might have seen a few bigger motors too (been over 40 years since I made a living doing that), but the rubber in the hub would slip a half-turn then grab. I want to say when you looked at the side facing the gearcase, the hub wasn't well centered in the aluminium propeller any more... I imagine running a jumping clutch dog for a while can break the hub loose and reproduce the jumping symptom... I've been far happier dealing with Velvet-Drive and a .002" feeler gauge... -W [/QUOTE]
