From the photo of the prop, the blade appears to be solidly fixed to the hub.. nothing variable there? Can you send better pix of the blade to hub junction area

Dave Bernard has a guy who fixes prop huba too. His name is Dave too, if he sees this.
The aluminum retaining ring should be flat side up and just needs to oriented so that the holes in the ring would align with the mount holes in the magneto with the top cylinder coil toward the front of the motor. I’ve never known what the notch in the retaining ring was for. When you install the flywheel is the magneto plate free to rotate? One time I got things all bound up when I installed the magneto and had the throttle link arm folded up under the mag plate. See attached pic to be sure the link arm isn’t folded underneath and making the mag plate and flywheel sit high. Abother possibility might be a bad taper on the flywheel hub. I had one with a wallowed taper where somebody had installed a shim piece in the hub in an attempt to fix it – see pic. The shim piece made the flywheel sit high on one side. Finally, is the flywheel key properly aligned and engaged?

seen some folks drill a small hole both sides of the prop body and drive a pin into the rubber hub to lock it in place … just use a shear pin instead of a solid drive pin.
temporary fix till you get a new prop.
but check for prop repair shops …if any for a new new rubber insert

I finished this one up last November after the test barrel was
put away for the winter, so it’s the first time in the water for this one
since I had it for a few years.
This one has the neutral shift, which I was suspicious of if
it was working correctly, as I could hear the motor revving
up. Turns out that it was the prop slipping on it’s plastic hub.
I “think” I got it fixed after this video, but have not retested it yet.
This motor had the “tall” Elgin water pump impeller, that was shot,
and I replaced it with two mercury impellers stacked together,
on a suggestion from Brian Wilcox. It seems to pump water great.
It has a tiny tell-tale at the exhaust cover, but blow out lots
of water out of a series of holes in the exhaust, just above the
water line.

Speaking of spun hubs, has anybody tried epoxies or silicone or urethane? I have a OMC brass prop that goes on 25 to 40hp motors from 1950 to ’70 or maybe more. It needs to be re-hubed. I don’t need it but it would be nice to have it fixed! The last one I had fixed cost 65 bucks. I know urethane has some good adhesion and it would cushion some also. Any thoughts on this idea?

some prop shops can repair it but…. it is old and they may or may not have what it takes.
ask around
seems I saw a solution some time ago …drill a hole (off center) across the prop body and hub and insert a pin or screw to lock hub and prop together. 2 likely need to balance the prop !
change the propeller shaft drive pin for a brass pin because you will no longer have hub slipping to protect the prop shaft and gears

Followed the instructions and sure enough the prop is slipping on the rubber hub. Is there a way to fix this or do I need to replace the prop.
Thank you for all the replies I appreciate it.

If it acts like it looses its grip on the water when you increase the throttle, the propeller may be slipping on its hub. There is a piece of rubber between these parts that you usually cannot see. This rubber goes bad and it will behave like it went into neutral when you put a load on it. Some propeller repair shops can fix this, or you can buy a new prop at places like http://www.propcopropellers.com. Take the prop off and mark the hub and prop position with a scratch or a permanent marker. Run it again and see if the marks still line up, or if it slipped.
