Performance Benefits

The SpitFire 4-Blade Aluminum Propeller changes what you expect from a small-engine setup. Its four-blade design digs in, gripping the water with authority and getting you on plane up to 25% faster than most three-blade props. That means less bow rise, more control, and a quicker transition from idle to speed.

Once you’re up and running, it’s all about balance. The prop’s blade geometry creates smooth, even lift, keeping your boat stable and predictable through turns, waves, and chop. You’ll feel tighter control at midrange speeds and a steadier ride when conditions get rough. It’s engineered for those who want more than just propulsion — it’s about connection, precision, and confidence every time you push the throttle forward.

Durability is another area where this prop shines. Mercury’s Mercalloy aluminum strikes the perfect balance between strength and flexibility. It’s resilient enough to handle small bumps or shallow scrapes, yet light enough to maintain efficiency and speed. Pair that with the Flo-Torq Reflex Hub System, and you get an added layer of drivetrain protection that absorbs shock from underwater impacts. That’s fewer repairs, less downtime, and more reliable time on the water.

Why This Prop Is a Strong Choice vs. Alternatives

• Quick Acceleration: Up to 25% faster hole shot than traditional three-blade props.
• Steady Handling: Four-blade design maintains grip and stability through turns.
• Tough Yet Forgiving: Mercalloy aluminum resists corrosion and handles minor impacts.
• Efficient Power: Blends lift, top-end speed, and fuel efficiency for well-rounded performance.
• Added Protection: Flo-Torq Reflex Hub cushions the drivetrain against impact damage.

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 lift and control of a four-blade prop with the speed of a three-blade design. It gives you faster acceleration, smoother handling, and better grip in all conditions.

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

If you run a lightweight fishing boat, compact runabout, or small pontoon powered by a Mercury engine between 25 and 40 HP, the 10.6" x 12" pitch offers a great balance of speed and control.

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

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

Q5: What hub system does it use?

It includes Mercury’s Flo-Torq Reflex Hub Kit, which helps absorb impact shock and protect your drivetrain while allowing for quick and easy prop changes.
