NEW Hub System NEW Technology for Big Engines with Big Prop Shafts For Mercury Applications with 1.25” Prop Shafts 150-400+hp with 4.75-5.44” Gearcases Running Stainless Steel Props Great replacement for Flo-Torq  1.25” HD Hubs and with other brands A solution for stainless steel props but works great with aluminum props too. MasterTorq™ (patent pending) 621 FSH™ Fat Shaft Hub™ has been Engineered for Mercury applications using a 1.25” Prop Shaft. For the first time Dealers rigging Mercury  Verado  or ProXS  engines with larger prop shafts now have access to Turning Point Propellers’ sought-after high performance Express stainless steel line of propellers (Hustler aluminum propeller housings are also compatible). Props paired with MasterTorq FSH’s new high-tech solid stainless steel spindle with replaceable low-cost cushioned material inserts provide an opportunity to last longer or even a lifetime compared to the competition. If the cushioned material inserts wear over time, simply replace them by hand, versus having to purchase a whole new hub like other competitive designs seen in the market. Installation made easy with this hub design; no hub press machine needed. At boat side, the hub can be installed into the prop housing with a hammer and removed the same way. Industry leader Turning Point Propellers, creator of the first prop with a drop-in hub system, is once again elevating propeller hub technology with its state-of-the-art technology – a less complicated more cost-effective solution over competitive designs.
