I have a Mercruiser Bravo 1 and I just bought a Solas Prop w. a Rubex 107 Hub Kit...

Bought it on Craigslist. Was mostly interested in the prop and was intending on buying a Merc hub kit. The RBX 107 hub kit is marketed as a Honda specific hub kit. But when I got home, I put the hub on the Bravo shaft and the splines mated perfectly. It's my understanding that Mercruiser uses a Flo Torq Hub assembly. Does this design cross into other brands as well? Is this kit useable on my Bravo 1?

Lower left side of the image below says interchanges with Mercury Flo-torque and michigan vortex propellers so that part should be okay for you.

But be careful with what thrust washer you use because in the parts list between the 107 for Honda and 102 for Mercruiser drives, the part numbers are different indicating a size difference but not sure which way the size goes. Though both Honda and Merc are listed in the 102 hub-kit, Compare all the part numbers between the two to help get an exact match to fit your application the best to avoid either damage or performance issues.

^ Also notice the aft spacers and nut differences as the 107 shows a cotter pin type installation.

You need to be sure the prop doesn't go to far down and rub (cut) into the lower gear case housing components...You also don't want the prop to stick to far out/away (Big Gap) from the gear housing either as overall performance may be lost too.

Wow. Thanks for all the great info Fun Times. I think that pretty much explains everything. I think I'll just play it safe and buy the RBX-102 kit.
