Performance Benefits

The SpitFire 4-Blade Aluminum Propeller redefines what small-engine boating feels like. It grabs the water with precision, putting your boat on plane quickly and confidently — up to 25% faster than comparable three-blade props. The moment you push the throttle, you’ll feel the immediate response: a clean surge forward, steady lift, and a tight, predictable connection to the water.

Once you’re cruising, the prop’s four-blade design comes alive. It smooths out vibration, holds strong through turns, and maintains balance even in rough or shifting water. You’ll notice how stable the boat feels — no slipping, no wandering, just solid, steady tracking. That confidence carries through every throttle change, every turn, and every stretch of open water.

Durability is another reason boaters trust this Mercury propeller. The Mercalloy aluminum alloy is both strong and forgiving, able to handle the bumps and scrapes that come with real-world boating. It resists corrosion and flexes just enough to absorb minor impact without compromising performance. The built-in rubber bushing hub adds another layer of protection, softening vibration and shielding your drivetrain from sudden shocks. It’s smart engineering that keeps you on the water longer, season after season.

Why This Prop Is a Strong Choice vs. Alternatives

• Faster Acceleration: Up to 25% quicker hole shot compared to standard three-blade props.
• Better Grip & Handling: Four blades provide smoother control and tighter turning.
• Durable & Forgiving: Mercalloy aluminum resists corrosion and impact damage.
• Balanced Efficiency: Delivers lift, speed, and fuel-friendly cruising performance.
• Drivetrain Protection: Rubber bushing hub absorbs vibration and impact shock.

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

If you’re running a small fishing boat, compact runabout, or lightweight pontoon powered by a Mercury 25–30 HP engine, the 9.3" x 9.5" pitch offers excellent overall performance and acceleration.

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

Yes. The corrosion-resistant Mercalloy aluminum alloy is designed for both environments. Just rinse the prop after saltwater use to extend its life and maintain its smooth finish.

Q5: What hub system does it use?

It features a rubber bushing hub system that absorbs vibration and cushions the drivetrain from minor impacts, reducing stress and improving overall ride comfort.
