Slipping prop troubles

Update, prop is back on with new key on place. Worked flawlessly when my son took out for a sail around Charleston yesterday. He said it was nice to have positive control in and out of the slip again!

Egads Leo!
That key has nothing square about it left! It is barely even straight.
No wonder you were having problems.

It is good to fix these 20 year (hopefully) maintenance items like this. Good work.

Yep, it was the key. Very worn. Diver is replacing this week and we should be back in business! Thanks!

If you are doing it yourself you can find a lot of keyway stock here: McMaster-Carr
Measure carefully.

Fix it quickly, friend.
It will make an awful mess of the prop and/or shaft taper.

leogallant Thanks guys, that's what it seems to be doing. By the way, its a Vetus M3.10 diesel.

If the shaft is indeed spinning properly in each direction, then it's time to pull off that prop and have a "look see". Hopefully it's like Caleb shared and it will be an easy fix. Either way, someone's getting wet!

Re: Slipping prop troubles

I'd guess that the keyway under the prop has disintegrated.
Take a look at the very bottom of this link: Propeller Shaft

Atomic 4 in that Newport 30' or a repowered diesel?
