Finally got the old girl out today. Had replaced the pinion gear when i first got it as it was wiped out, all else looked good. Ran great at low speed, hit the main channel and let it rip, I know some of you are gonna snicker at this, but that darn lil 20 hp motor got up and went! So I'm cruising along, backed off the throttle a bit, and a mile or so into the trip, I high a whine, the rpms go up and the boat slows down, so I backed off, but every time I got in it, same thing, so I'm thinking the gears again, but its fine at low to almost medium speeds. Old Johnson handbook says maybe the prop is slipping. Yes? No way? What would I look for? Or just buy a new one? Thanks, this was the best half hour in a long time!

It's not uncommon to spin a prop hub. It will usually exhibit the symptoms you describe. May hold at low/moderate speed, but will slip at high(er) rpm. Try another prop, and have it repaired..

well that is 2 for the prop so far, thing is, I took itoff, to me it all looks like one solid welded piece to me?? All thats there is the prop, slidesonto the shaft and catches the shear pin at the base, screw the locknut on and put the cotter pin in. Is it possible to expand out and away rom the shear pin? Thanks guys,this is my first boatof my own and seasoned advice is helpfull!

You have a splined insert in the prop? Which you do, then you have a spun prop.
Unless prop is near new wouldn't bother repairing it. A new OMC aluminum prop for a 20 shouldn't be more than $75. Dealer may even have a used or repaired for a lot less.

$75 is alot when a hub rebuild usually only goes for $35. If the prop is nicked and bent, then keep it as a spare to limp you home and spring the $75 for new. Otherwise, find a prop shop to rebuild it, that's what prop shops do... One other recent thread had a guy in TN who found one locally in the yellow pages, they're everywhere...

Same thing happened to me on my first day out with my "new" used 13'. It was the prop! The prop had a number of nicks so the cost of refinishing + insert was almost the price of a new prop. I went with the new prop...
