Alpha one Gen 1 Prop movement

[ukstu]

Morning Mercruiser guru’s.
A question for a friend. He has noticed his pro is loose on the shaft. Tightened up, but there is a bit of movement, too much.
Do the flo torque hubs wear out and can cause this?
He’s not removed the prop yet, that will be done at the weekend so will hopefully show something obvious but thought I’d ask some advice first?

Many thanks

Once the prop nut is tight there should be no movement of the prop on the shaft, but there should be a slight bit of in/out play of the shaft

So, from the video that I’ve seen (which I can’t upload for some reason), the nut is tight, but when holding one of the blades, there is movement. Not the slight in outplay that I also understand to be normal. It’s definitely too much play in the wrong direction.

If it wobbles you have a problem.

Any idea what the problems could be? I guessed he probably has a problem.
Just trying to get some ideas before the weekend when I can see it and he gets the prop off.

Ayuh,... The only answer is to pull the prop, 'n look,.....
