Mercury – Quicksilver 82670911 Prop Nut | Stainless Steel | Mercury 3.6–110HP Outboards | 82670911

Overview

A secure prop nut isn’t just about keeping your prop in place — it’s about getting every ounce of power to the water. The Quicksilver 82670911 Prop Nut is built for Mercury outboards (3.6, 3.9, 39, 40, 60, and 110HP) and made from tough, corrosion-resistant stainless steel.

This is the same kind of nut Mercury installs at the factory, tested to handle more torque and stress than most aftermarket parts ever see. It’s simple, durable, and built to stay tight so your prop won’t go anywhere, no matter how hard you push your boat.

Key Features

• Purpose: Keeps your propeller locked down tight so all your engine’s power transfers cleanly to the water.
• Material: Made from hardened stainless steel that holds up against rust, salt, and repeated torque.
• Performance: Tested beyond Mercury’s torque limits to handle years of hard running without loosening or galling.
• Design: Precision-machined threads give it a snug, balanced fit that helps prevent vibration.
• Ease of Use / Install: Threads easily onto the prop shaft — quick to install or swap out with standard tools.

Engine & Boat Compatibility

• Mercury outboards: 3.6, 3.9, 39, 40, 60, and 110HP
• Common on small cruisers, fishing rigs, and family runabouts

Performance & Real-World Benefits

The 82670911 prop nut gives you peace of mind every time you throttle up. Once tightened down, it won’t back off or loosen, even in rough water or heavy vibration. The stainless-steel build stands up to both salt and freshwater without corroding, so it’s made to last through seasons of use.

Replacing a prop nut might seem small, but it’s the kind of detail that keeps your setup dependable. With a fresh OEM nut, you’ll know your prop’s staying right where it belongs — secure and spinning true.

Why Choose OEM

Mercury’s hardware is engineered to match their prop shafts perfectly. Cheaper hardware can strip threads, loosen under load, or rust out after one season.

A genuine Quicksilver prop nut fits right, lasts longer, and meets Mercury’s torque and corrosion standards. It’s the kind of part you install once and don’t have to think about again.
