Quicksilver Propeller Parts & Accessories: OEM-Quality Hardware for Your Marine Drive

A propeller is only as reliable as the hardware holding it in place. Quicksilver, the premier OEM-aligned parts brand under Mercury Marine, brings that same factory-level engineering to its line of propeller parts and accessories — giving boaters the confidence that every component behind the prop is built to the same standard as the prop itself.

The Flo-Torq Hub System: Quicksilver's Flagship Propeller Technology

At the heart of Quicksilver's propeller parts lineup is the renowned Flo-Torq hub kit family. Quicksilver Flo-Torq propeller hub kits are designed for use with many of the most popular Quicksilver and Mercury props on the water, and the selection includes Flo-Torq SSR hub kits, which offer quieter shifting and smoother operation than traditional hub kits.

The SSR (Soft-Shift Rubber) designation represents a meaningful technological leap. The SSR hub utilizes Quicksilver's proven Soft-Shift rubber technology to prevent shifting noise, vibration, and harshness, delivering a 22–23% reduction in shift event noise — virtually eliminating shift clunk. For boaters who spend long hours on the water, that difference in refinement is immediately noticeable.

The Flo-Torq line spans multiple generations and configurations to cover an exceptionally wide range of engines. The Flo-Torq II hub kit is designed for use with high-horsepower Mercury outboards and MerCruiser stern drives with 400+ hp. At the same time, the Flo-Torq SSR HD hub kit fits select 200 hp through 400 hp Mercury FourStroke outboards with 1.25" propeller shafts. Beyond Mercury platforms, the Flo-Torq II hub kit family also adapts Mercury and Quicksilver propellers for use on OMC Cobra and Volvo SX stern drives.

Complete Kits with Everything You Need

One of the practical advantages of Quicksilver hub kits is their completeness. Each kit typically includes the SSR drive sleeve, a three-washer set (washer, thick washer, and cupped Belleville washer), a tabbed lock washer, and a locking prop nut — so there's no hunting for individual fasteners. Flo-Torq hub systems are durable, provide lower unit protection, and are also field serviceable , making them a practical choice for both marina professionals and do-it-yourself boaters alike.

Thrust Washers and Supporting Hardware

Beyond hub kits, Quicksilver's propeller parts catalog extends to individual components like thrust washers and continuity washers. The Quicksilver continuity washer 423511, for example, can be used on 135–275 hp Mercury and Mariner outboards as well as MerCruiser Alpha One and Bravo One sterndrives using Flo-Torq I hubs. These smaller components play an outsized role in maintaining drivetrain integrity and protecting against galvanic corrosion — details that matter greatly in both saltwater and freshwater environments.

Cross-Platform Compatibility

Quicksilver, a division of Mercury Marine, produces high-quality propeller accessories for many motor manufacturers including Yamaha, Evinrude, Tohatsu, Suzuki, Honda, and Volvo Penta. This broad compatibility means that even boaters running non-Mercury power plants can take advantage of Quicksilver's engineering pedigree and field-proven hub technology.

Whether you're replacing worn hub hardware after a season of hard use or upgrading to the latest SSR generation for a quieter, smoother ride, Quicksilver propeller parts deliver the fit and function of OEM components with the wide availability of an aftermarket brand.
