I threw the counter rotating prop off my Bravo XR drive last weekend when my "Stern Lock" prop lock spun off. This is the second time this has happened. (I thought it was my fault the first time.) Never again!

Anyway, in replacing everything the question is coming up if I should be using the "heavy duty" hub set that Merc offers for the Bravo. This is going into a stock Bravo 1 prop. I didn't know they made a standard and heavy duty.

Any advice?

Thanks - JON

For the 1 inch prop shaft you can use the Flo Torq Hub which has a Nylon sleeve or the Solid Hub which uses a stainless steel sleeve. The Stainless Steel sleeve is recommended for 400 + HP.

For the 1" shaft with 15 splines. There are 2 different hub kits

835258K1 and K2. You probably need the K2


For 1.25" HD shaft with 19 splines.

840389K06

We have them all if you need help finding them.

XR hub kit is for the 1.25 shaft.

Oops, it's a XR, thanks Julie,

Yes, you will need the 840389K06 for your XR

Have to use the HD with the big shaft.
