i run a 68 fastwin on a 69 Alumacraft in Charleston inland waters. mostly shrimping and crabbing. i run in shallow waters. alot hitting sandbars etc. Normal ops around here. i'm cheap. i have a few old props out in the barn. One or two still look good except they are spun. 1 in particular looks as though i could use some industrial strength cement or epoxy and press it back together. i'm going to give it a try and see what happens. i'll keep you updated.
Anyone else ever try this?
Any sugestions on adhesives etc?
again this is an experiment (and yes, a spare prop & pin will be on board).
let me know.

Re: pin drive prop experiment

I'm thinking along the same lines, except I am considering fabricating a solid hub that will lock it up and never slip. One thing I'm hesitating on is the rubber is supposed ot absorb some of the "clunk" when shifting into gear. How effective it is at that, I don't know. But in theory at least, a locked-up probeller could be hard on clutch dogs.

Re: pin drive prop experiment

F_R i've been reading your posts for a long time and if you are saying you think it's worth a try then that's all the encouragement i need. i agree that the rubber is in there for a reason and that is obviously to absorb the shock of shifting and hitting objects other than water. i too have considered making a solid connection but, around here that might be a bad idea. much rather fix a prop than a motor. my 1st concern with this what adhesive / cement would be strong but still have some give. any ideas?

There has to be some adheasive that the re-hubbing shops use. Just how do we shadetree mechanics find that out? Maybe they want to keep that pretty much a secret.

They don't use any adhesive. They buy the hub already bonded and just press it into the prop. The hub consists of the bronze center part, and the rubber cushion. They are bonded together when the cushion is formed from liquid or whatever it comes from. When the bond rips apart, that is when it slips.
