Overview

You can always tell when your prop is dialed in just right. The boat leaps forward, grips the water like it was born for it, and you feel that steady pull of clean, confident thrust. That's exactly what you get with the Mercury SpitFire 4-Blade Aluminum Propeller. It is designed for small outboards but delivers big-league performance — faster acceleration, smoother handling, and sharper control. Whether you’re navigating quiet morning coves or running across open water with a full load, the SpitFire keeps your boat balanced, responsive, and ready for anything the day brings.

Performance Benefits

The SpitFire 4-Blade Aluminum Propeller redefines what you expect from a small-engine setup. This isn’t your average four-blade prop. Its advanced blade design grips the water tighter, pushing your boat onto plane faster than you’d think possible for its size. Acceleration feels crisp, the lift is immediate, and handling becomes second nature.

Once you’re up and running, the difference really shows. The four blades keep the boat stable, slicing through turns and wakes with smooth precision. Even in choppy conditions, the SpitFire holds steady, keeping your control sharp and predictable. It’s a prop that doesn’t fight you — it works with you.

Mercury’s proprietary Mercalloy aluminum makes this prop tough yet forgiving. It is strong enough to handle impact, but flexible enough to absorb the shock from those inevitable shallow-water surprises. That means fewer repairs, more time on the water, and long-lasting reliability. Pair that with the Flo-Torq Reflex Hub Kit, and you’ve got an extra layer of protection for your drivetrain that can make the difference between a small bump and a big repair bill.

Why This Prop Is a Strong Choice vs. Alternatives

• Faster Acceleration: Delivers up to 25% quicker hole shot than most three-blade props.
• Smooth Handling: Four-blade geometry gives steadier turns and better balance at any speed.
• Durable and Forgiving: Mercalloy aluminum resists corrosion and handles minor impact with ease.
• Efficient Design: Balances speed, lift, and responsiveness for reliable all-around performance.
• Built-In Protection: Flo-Torq Reflex Hub cushions the drivetrain against shock from impacts.

FAQ Section

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

It’s built for Mercury and Mariner 25–30 HP FourStroke BigFoot/Command Thrust outboards, 30 HP TwoStroke and FourStroke models (2005 and newer), and 40 HP outboards.

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

The SpitFire combines four-blade grip and control with the top-end speed of a three-blade prop, giving you faster acceleration, smoother cruising, and improved lift.

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

If you run a smaller fishing boat, lightweight runabout, or compact pontoon powered by a Mercury outboard between 25 and 40 HP, the 10.6" x 11" pitch delivers excellent all-around performance.

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

Yes. The Mercalloy aluminum alloy is corrosion-resistant and performs well in both environments, though rinsing after saltwater use is always recommended.

Q5: What hub system does it use?

It uses Mercury’s Flo-Torq Reflex Hub Kit, which absorbs shock from minor impacts and helps protect your engine’s drivetrain.
