MC-1 Propeller/Thrust Hub Seal?

[998cc]

All, I am replacing my aluminum prop with a stainless steel prop of another identical MC-1 drive. My aluminum prop has a rubber seal that mates up to the thrust hub. The stainless prop has what appears to be the remnants of a seal in the same location. I can't find a seal in the Mercruiser Service Manual Vol. II page 6A-3. (Perhaps the wrong section?) Does anyone know a part number for this seal or know where it is listed in the service manual? If it is not a seal, what is it?

Thank you.

Ayuh,.... Donno what yer seein', but there ain't no thrust hub seals,.....

There Are different thrust hubs,..... If it fits, it's right, if it looks wrong, it's probably the wrong one,.....

Hello Bondo. Thanks for the response; now I am really confused...;-) It looks like it could be a big fat O-ring; perhaps it is something a P.O. had put in there for whatever reason? If it is not needed, that's just as well. Here is a photo:

Ayuh,... That's part of the hub, the pressed in rubber hub,...

Thank Bondo. Looks like there are no worries. The newer prop will go on.

All the best.

There are a few thrust hubs, only the correct one fits without damaging anything

I installed the stainless prop, and it works a treat! Just wanted to close out the thread. Thanks!
