The Mercury SpitFire 4-Blade Aluminum Propeller captures that feeling every single time. Built for small outboards yet packed with the precision and punch of Mercury engineering, this prop delivers crisp acceleration, balanced lift, and steady control from start to finish. Whether you’re chasing fish at dawn or heading back through late-day chop, the SpitFire gives your boat the kind of response that makes you want to stay out longer.

Performance Benefits

The SpitFire 4-Blade Aluminum Propeller is proof that small props can pack big performance. With its aggressive blade design, it bites into the water with precision, pulling your boat onto plane faster — up to 25% quicker than a comparable three-blade propeller. The lift feels immediate, the thrust is smooth, and the response is instant when you throttle up.

Once you’re cruising, that same design keeps you steady and in control. The four blades work together to smooth out vibration and maintain grip, even when cutting across chop or making tight turns. You’ll notice how easy it feels to steer — no slipping, no struggle, just balanced power and predictable motion. It’s the kind of control that makes long days on the water less tiring and a lot more fun.

Durability is where this prop really earns its keep. Mercury’s Mercalloy aluminum gives you the best of both worlds — lightweight efficiency with the resilience to handle real-life boating. It resists corrosion, shrugs off small bumps, and keeps performing season after season. Pair that with the Flo-Torq Reflex Hub Kit, and you’ve got built-in drivetrain protection that absorbs impact shock from underwater strikes, reducing wear and potential damage. This prop doesn’t just run smooth — it’s built to last.

Why This Prop Is a Strong Choice vs. Alternatives

• Faster Acceleration: Up to 25% quicker hole shot compared to standard three-blade designs.
• Smooth, Predictable Handling: Four blades hold steady through turns and waves.
• Durable & Forgiving: Mercalloy aluminum resists corrosion and minor impact damage.
• Balanced Efficiency: Combines lift, speed, and fuel economy for versatile performance.
• Built-In Protection: Flo-Torq Reflex Hub cushions your drivetrain against underwater impacts.

FAQ Section

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

It’s compatible with 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 blends the control and bite of a four-blade design with the top-end speed of a three-blade. It’s engineered for faster acceleration, better lift, and a smoother ride across all speeds.

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

If your boat is a small fishing setup, compact runabout, or lightweight pontoon powered by a Mercury engine between 25 and 40 HP, the 10.1" x 15" pitch delivers excellent balance and performance.

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

Yes. The corrosion-resistant Mercalloy aluminum alloy performs reliably in both environments. For saltwater use, a quick rinse after each trip helps preserve its finish and performance.

Q5: What hub system does it use?

It includes Mercury’s Flo-Torq Reflex Hub Kit, designed to absorb shock from minor impacts and protect your drivetrain while allowing quick and easy prop changes.
