Flo-Torq SSR HD
Introducing the Flo-Torq Soft Shift Rubber (SSR) HD, the next generation of Mercury Propellers’ Flo-Torq Hub Systems. The Flo-Torq SSR HD is the quietest and smoothest shifting propeller hub system in the market for high horse-powered outboards. In fact, the Flo-Torq SSR HD delivers a 10-19% shift clunk improvement vs. other noise reduction rubber hub systems and a 25%+ improvement vs. solid hub designs.
The Quietest and Smoothest Hub System Ever Created
During shifting events such as when using JoyStick Piloting for Outboards and/or shifting into gear, the Flo-Torq SSR HD rotates both port and starboard - eliminating shift clunk and vibration for quiet and smooth shifting. Once under load, the hub will engage the propeller inner hub, resulting in a solid hub with the ability to transfer the power of
- Mercury Verado Six Cylinder 300 hp and 350 hp
- Mercury Racing Verado 400R
- Mercury OptiMax Pro XS 225 hp and 250 hp
Flo-Torq SSD HD can be used on all high-horsepower applications such as center console, bass, multispecies, bay/flats, deck, tritoon/pontoon, RIB, and sport boats. It can be used with Mercury propellers Bravo I, Enertia, Enertia ECO, Fury, Revolution 4, Mirage Plus, and Tempest Plus.
A Higher Grade of Performance
Mercury transforms aluminum and stainless steel into the highest-quality, best-performing, most-durable marine propellers in the world. Also the best-selling, no surprise. Our experience, expertise, and proprietary technologies – Flo Torq®, Mercalloy®, X7® alloy, and PVS® (Performance Vent System) – give you a true competitive advantage. For best overall boat performance, there's no substitute for a Mercury Propeller.
Producing world-class Mercury propellers is no simple task
X7 Alloy: Designed to do the impossible.
Making Rules. By rewriting the rules. Thirty-percent stronger and four times more durable than conventional stainless steel, Mercury's revolutionary X7® alloy makes the impossible possible. Prop designs that couldn't be done. Performance levels that couldn't be reached. Now within your grasp.
Flo-Torq® II: Hidden Protection
Mercury's Flo-Torq propeller hub might just be the most important part you never see. Not only does it flex during shift changes, reducing noise and vibration. If your prop hits an underwater object, it sacrifices itself to save your lower unit. Just pop in a new hub and you're back on the water, no service call needed. The Flo-Torq hub also makes Mercury propellers compatible with most engines on the market while also providing unmatched corrosion protection.
PVS® (Performance Vent System). A Mercury-exclusive innovation for custom tuning and venting your propeller to match your engine.
Just by varying the size of the exhaust hole and controlling your engine’s rpm, you can eliminate sluggish performance or compensate for changes in load in altitude. And it’s technology that you can only get with Mercury Propellers.
You can order all available Mercury literature online or through any authorized Mercury dealer. Please have your outboard or sterndrive serial number before placing the order.
