Performance Benefits

The SpitFire 4-Blade Aluminum Propeller brings new life to your small-boat setup. It’s built to grab water with authority, delivering quicker acceleration — up to 25% faster than comparable three-blade props. That means you’ll get on plane faster, enjoy more responsive steering, and feel a tighter connection between throttle and movement.

Once you’re running, this prop delivers a ride that feels composed and confident. Its four-blade layout creates lift that steadies the boat through turns and waves while maintaining a smooth, predictable response at cruising speeds. You will notice how it grips through chop without slipping and tracks straight even when the water gets unpredictable. It’s the kind of performance that inspires trust — the boat simply feels tuned in.

Durability is built into every inch of this Mercury propeller. The patented Mercalloy aluminum strikes an ideal balance of toughness and flexibility. It’s strong enough to resist corrosion and absorb the occasional bump from shallow debris, yet light enough to keep your engine working efficiently. Add in the Flo-Torq Reflex Hub Kit, and your drivetrain gains an extra layer of protection against shock impacts. That’s peace of mind on the water — fewer repairs, smoother operation, and long-term reliability.

Why This Prop Is a Strong Choice vs. Alternatives

• Faster Takeoff: Up to 25% quicker hole shot compared to most three-blade designs.
• Confident Handling: Four-blade design keeps control steady through turns and chop.
• Durable and Forgiving: Mercalloy aluminum resists corrosion and minor impacts.
• Balanced Performance: Smooth acceleration, reliable lift, and efficient cruising.
• Protected Drivetrain: Flo-Torq Reflex Hub absorbs shock from underwater strikes.

FAQ Section

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

It’s made 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 the control of a four-blade prop with the top-end speed of a three-blade. It delivers smoother acceleration, better lift, and tighter handling across the power range.

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

If you run a small fishing boat, light pontoon, or compact runabout powered by a Mercury outboard between 25 and 40 HP, the 10.1" x 14" pitch is an ideal fit for all-around performance.

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

Yes. The corrosion-resistant Mercalloy aluminum performs well in both environments, though rinsing after saltwater use is recommended for long-term protection.

Q5: What hub system does it use?

It uses Mercury’s Flo-Torq Reflex Hub Kit, which cushions the drivetrain from impact and makes prop changes quick and easy.
