Mercury – Quicksilver 835257Q6 Flo-Torq II Hub Kit with Bushing | Mercury 135HP+ Outboards (Surfacing Applications) | 835257Q6

Overview

When you’re running a big motor and pushing high speeds, you need parts that can take a beating. The Quicksilver 835257Q6 Flo-Torq II Hub Kit is built for Mercury 135HP and larger outboards that use surfacing prop setups — the kind of applications where the prop leaves the water and comes back under full power.

This hub takes the shock out of every hit, protecting your gears while keeping your prop running true. It’s tough, proven, and simple to service right at the dock if you ever need to swap parts after an impact.

Key Features

• Purpose: Cushions your drivetrain from impact and torque stress in surfacing and high-speed prop applications.
• Material: Built from reinforced Delrin with corrosion-resistant stainless hardware that won’t crack or deform under load.
• Performance: Handles heavy torque and high RPM without vibration, keeping the prop tight and the ride smooth.
• Design: Includes Flo-Torq II hub sleeve and bushing made specifically for Mercury 135HP+ surfacing outboards.
• Ease of Use / Install: Straightforward setup — drop it in, tighten it down, and you’re ready to run; fully field-serviceable.

Engine & Boat Compatibility

• Fits Mercury 135HP and larger outboards
• Designed for surfacing propeller and performance applications
• Works with Mercury and Quicksilver propellers
• Common on offshore boats, bass rigs, and high-speed performance hulls

Performance & Real-World Benefits

The 835257Q6 hub kit helps protect your lower unit when you’re running hard. In surfacing setups, the prop is constantly leaving and re-entering the water, creating shock every time it bites again. This hub absorbs that shock, keeping your gears safe and your prop steady.

If you do hit something or wear the bushing, you can replace it in minutes — right there on the boat ramp or dock. It’s a small part that can save you from major repairs and downtime.

Why Choose OEM

Mercury’s Flo-Torq system is engineered for real-world punishment. It’s been tested on racing boats, offshore rigs, and high-output outboards, so you know it’ll hold up. Aftermarket hubs might fit loosely or wear unevenly, leading to chatter or failure.

A genuine Quicksilver Flo-Torq II kit guarantees the right materials, balance, and fit — the same level of quality Mercury builds into every high-performance engine.
