Mercury – Quicksilver Prop Washer | Propeller Hardware | Stainless Steel | 161402

Overview

You don’t notice a good prop washer until you need one. The Mercury Marine 161402 Quicksilver Prop Washer does its job quietly — holding your prop tight, transferring every bit of power, and keeping the system running smooth. Built from hardened stainless steel, it’s made to take years of torque, vibration, and saltwater without bending, rusting, or losing its grip. It’s one of those small parts that make a big difference in keeping your boat feeling solid and predictable every time you throttle up.

Performance & Practical Benefits

A prop washer’s job is simple — hold everything tight and true — but it has to do it perfectly. The 161402 washer is thick, solid, and smooth, built to sit flat under the prop nut and keep the torque balanced. The stainless steel doesn’t rust or gall, even after years of hard use, so you can remove it later without a fight.

You’ll feel the difference in how smoothly the prop seats and how quietly the drivetrain runs. No movement, no vibration, no question about whether the prop is holding. It’s a small part that carries big responsibility, and Mercury builds it to take that job seriously.

Why Buy OEM

You can find washers that look the same, but “close enough” isn’t good enough for a part that keeps your propeller locked in place. The Quicksilver 161402 is a genuine Mercury Marine part, cut, hardened, and tested to exact factory specs. That precision means consistent torque, clean contact, and long-term strength under pressure.

Using OEM hardware ensures everything stays aligned and balanced, protecting both your prop and driveshaft from wear. It’s a simple upgrade that gives you confidence every time you run your boat — knowing your hardware is made for the job, not just made to fit.
