Mercury – Flo-Torq SSR Solid Propeller Hub Kit | High-Performance Prop System | Precision Marine Construction | 8M0101604

Overview

There is a moment every boater knows—the instant the prop bites, the boat lifts, and the whole hull comes alive. When that moment feels clean and controlled instead of jarring, the rest of the day on the water just seems to fall into place. That is exactly the kind of confidence the Quicksilver Flo-Torq SSR Solid Propeller Hub Kit 8M0101604 brings. It smooths out the rough edges of high-performance running, taming the hard shift clunk and tight vibrations that can wear on both your nerves and your drivetrain. Whether you are driving a lightweight bass boat or a powerful center console, the difference is immediately noticeable: quieter engagement, cleaner acceleration and a more connected feel with your engine.

Performance & Practical Benefits

High-performance boating has a rhythm all its own, and the SSR Solid Hub Kit helps everything fall back into sync. The Soft-Shift Rubber sleeve absorbs the sudden load of shifting, giving you a steady, quiet transition into gear. Instead of the usual hard “clunk,” you get a firm but gentle engagement that makes close-quarters maneuvering far more intuitive.

When you open up the throttle, the benefit becomes even clearer. The solid construction of the SSR hub maintains a strong, secure connection between the propeller and the engine, ensuring clean, steady thrust even when the prop is surfacing at speed. That translates to tighter handling, smoother acceleration and a more predictable ride when the water starts stacking up.

Durability is another major win. The SSR system helps shield the drivetrain from impact forces that come with aggressive running or unexpected contact with debris. Over time, that added protection means fewer surprises and more confidence every time you head offshore or up the river.

Why Buy OEM

With something as critical as the link between your engine and your propeller, aftermarket shortcuts rarely pay off. A genuine Mercury Marine part like the 8M0101604 hub is engineered around exact tolerances, proven materials and real-world performance testing. You are not just getting a hub—you are getting a part that works in harmony with your outboard, protects your drivetrain and keeps your boat behaving exactly the way Mercury intended. It is the kind of choice seasoned boaters make not for flash, but for peace of mind.
