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?

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.Prepare to be boarded!
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.
