Performance Benefits

The Mercury SpitFire 4-Blade Aluminum Propeller proves that small engines can deliver big performance. Its aggressive blade design grips the water firmly, pushing your boat onto plane up to 25% faster than a standard three-blade prop. The moment you ease into the throttle, you’ll feel the difference — smoother lift, clean thrust, and a steady surge forward that feels both powerful and controlled.

Once you’re underway, that same four-blade balance pays off in handling. Turns feel crisp and confident, even through chop or shifting currents. The prop holds tight in corners and tracks straight when you want it to, reducing the skidding or slipping that can make a small boat feel unpredictable. You’ll notice the boat stays planted and calm, letting you focus on the ride instead of fighting the wheel.

Durability is built into every inch of this Mercury propeller. The patented Mercalloy aluminum alloy combines strength with just the right amount of give, helping it resist corrosion and absorb small impacts without damage. The rubber-bushed hub takes things further by dampening vibration and cushioning the drivetrain from shock. Together, they create a setup that’s dependable, forgiving, and easy to maintain — a combination that keeps you on the water longer with fewer worries.

• Durable & Forgiving: Mercalloy aluminum resists corrosion and flexes to absorb impact.
