Mercury – Quicksilver Prop Nut | Propeller Hardware | Hardened Brass | 161472

Overview

Every bit of power your engine makes depends on one small connection — the prop nut. The Mercury Marine 161472 Quicksilver Prop Nut keeps your propeller locked in tight, transferring all that torque to the water where it belongs. Made from hardened marine-grade brass, it’s designed to handle years of vibration, pressure, and exposure without loosening or corroding. Simple as it is, this little part holds everything together — your power, your performance, and your confidence on the water.

Performance & Practical Benefits

A secure prop nut means you never have to worry about losing power — or your prop. The 161472 Prop Nut provides the tight, precise fit that keeps everything balanced and aligned. Its hardened brass construction won’t deform or seize, even under heavy torque and repeated removal.

You’ll notice how smoothly it threads on, how solid it feels when torqued down, and how easily it comes off when it’s time for maintenance. It’s built for the long haul, resisting corrosion, pitting, and thread wear — the kind of reliability you expect from Mercury hardware.

Why Buy OEM

It’s tempting to save a few bucks on small hardware, but few things matter more than the connection between your engine and your propeller. The Quicksilver 161472 is a genuine Mercury Marine part, tested to exceed factory torque standards and made from materials proven to survive harsh marine environments.

Aftermarket nuts might fit, but they don’t have the same precision or durability. A poor fit can cause vibration, stripped threads, or even propeller loss. With Mercury OEM hardware, you get exact fitment, tested performance, and confidence every time you put the throttle down.
