Re: '63 QD-24b Something is slipping while under power

Thanks Fishy55. As fate would have it, I'm having all the same problems you are with my '61 QD-22 10hp (same basic motor). The motor runs great in a test tank and shifts into/out of gear easily, yet doesn't really "lock" into place as solidly as it seems like it should. I've replaced the clutch dog and that didn't fix it. I've also adjusted and readjusted the shift linkage and I'm 99% sure that's good to go, so I guess I'm looking at a possible spun prop too? Were there any telltale signs that your old prop was bad (i.e. wiggly bits, broken shear pin or any obvious wear and tear), or did you just determine it by process of elimination? Thanks again for updating your thread.

The old prop seemed solid and had no signs of wear. It looked nothing like what samo_ott posted in his pictures. I couldn't make it slip by hand or anything. Never had a broken shear pin or something obviously wrong with it. Like you say, I basically took all things into consideration and by process of elimination was left with replacing the prop. I laid into her pretty heavy on the water, WOT everywhere I went. Opened her up from a standstill, seeing if it would slip again, but it never did. Hopefully that's all you need to keep yours on the water. I think I'm running about 20mph (GPS) with this new prop (8 1/2 pitch), pretty darn fast compared to my old 6hp 'Rude! Lemme know if I can be of anymore help.
