Reverse works. Forward works too, except when I increase the throttle. I
pulled the prop off and it is not splined. It has a pin that holds the prop
in position on the smooth shaft. There is no rubber hub, but there is what
looks like a bronze one. I don't think there is any way for the prop to
slip on the shaft, being that is held on by a steel pin through the whole
thing. Is there a shaft coupler that could possibly be broken?

Thanks.

It could be that the "dogs" on the forward gear are worn, and
dis-engage under load. If it's not the prop (remember, there is much
less load on a prop in reverse than at WOT) I would buy a manual and
drop and split the lower unit and inspect all gears.
