90 Merc gear case noise

If you have a 90Merc spinning a stainless prop you have probably noticed a lot of noise coming from the gear case. Merc now has a new prop hub that eliminates the noise. I've just installed one of their new Flo-Torque III hubs on my '03 Merc and noticed a dramatic reduction in engine noise, especially at speeds from idle to about 1500 rpm. The part number for the new hub is 835257K 9.
