Performance Benefits

The Quicksilver Nemesis 4-Blade Aluminum Propeller changes the way small outboards perform. From the first push of the throttle, you’ll feel it grab hold of the water with authority. Acceleration is quick — up to 25% faster than comparable three-blade props — and that extra punch translates to more control when getting on plane or navigating tight spots.

Once you’re cruising, the difference becomes even clearer. The Nemesis keeps your boat balanced and predictable, smoothing out vibration and holding tight through turns. It grips the water with confidence, giving you that feeling of connection that makes driving more intuitive. Whether you’re cruising calm water or slicing through afternoon chop, the prop stays steady, helping your boat track straight and true.

Durability is part of its DNA. Cast from high-strength aluminum and finished in Phantom Black, the Nemesis resists corrosion, scratches, and everyday wear. The material strikes the perfect balance between toughness and flexibility — strong enough to handle a bump or scrape, but forgiving enough to avoid lasting damage. It’s the kind of prop that performs just as well in its fifth season as it did in its first.

Why is this prop is a strong choice vs. alternatives?

If you’re looking for an aluminum propeller that performs like stainless without the price tag, this is the one. The Quicksilver Nemesis 4-Blade Aluminum Propeller delivers Mercury OEM quality at a cost that makes sense for real-world boaters. It’s reliable, easy to maintain, and designed to handle everything from early-morning launches to long days offshore. You’ll get quicker takeoffs, smoother handling, and better grip — all without sacrificing speed. It’s a prop that feels balanced, durable, and built for the kind of boating most of us actually do.

FAQ Section

Q1: Which Mercury engines does the Nemesis 4-Blade Propeller fit?

It’s designed for 25–30 HP Mercury FourStroke outboards (2006 and newer) and works with compatible Mariner, Honda, and Tohatsu engines when equipped with the correct thrust washer.

Q2: What makes this propeller different from other Mercury options?

The Nemesis is the world’s first performance-focused aluminum propeller, combining the lift and grip of a four-blade design with the top-end speed of a three-blade.

Q3: How do I know if this pitch or size is right for my boat?

If your current three-blade prop gives you proper RPMs, switching to the same pitch in a Nemesis will improve acceleration, control, and lift without losing top speed.

Q4: Can this prop be used in both saltwater and freshwater?

Yes. The durable Phantom Black finish protects against corrosion in both environments. A simple rinse after saltwater use helps maintain its finish.

Q5: What hub system does it use?

It’s compatible with the Flo-Torq Reflex Hub System, which cushions drivetrain shock and ensures smooth, quiet performance.
