Prop repair and proper terminology

[gazelle]

I banged up a prop the other week and got it repaired. When I sent it in to get repaired I sent (sorry do not know what it is called) the fitting that fits inside the prop and provides contact to the drive shaft of the motor. When I got the prop back they guy that fixed it did not return this piece.

What is this piece called and should I have gotten it back? I should note that it was separate from the prop when I sent it and the spare prop that I put on had the piece secured to it.

Should the piece be able to be removed or should it be secured somehow to the prop? Can I buy that piece without buying an entire new prop? I am guessing the repair man will say he no longer has it.

Is this the equivalent to a shear pin? If it is loose is it because of the rock I hit? If that is the case does that mean it was damages beyond repair? After hitting the rock I put the motor at just above idol to get back so I did not damage anything with the vibration due to the prop being out of balance. Since I could get back I assume that I did not break the sheer pin or equivalent since the prop spun to get me home.

The motor is a 1997 force 90 hp

Sorry for the newby question, I would just like to talk some whet intelligently to the repair man so he knows what I am talking about and so I know what he should or should not have sent back.

Thanks

It is called a Thrust Washer. It is a separate piece but sometimes they corrode and stick in the back of the prop. Prop man probably lost it, but can't hurt to ask. When you install a new one, coat it with anti-seize. They sell for about 10 bucks. Don't leave it off. Without it, the prop will rub on the gearcase and wear it.

If it's a plastic piece that goes inside the prop hub it's the "Flo-Torque" drive sleeve. Flo-Torque kits are available at most marine dealers and sporting goods departments that sell boating supplies.
