Mercury Spitfire X7 Propellers

Mercury Spitfire X7 Propellers

Step up from aluminum to true stainless performance. Mercury’s Spitfire X7 propellers use a high-strength X7 stainless alloy and a refined 4-blade geometry to deliver faster hole shot, added stern lift, and planted cornering. The result is crisper acceleration and steadier control for small and mid-horsepower outboards across a wide range of hulls.

Why Choose Spitfire X7

• X7 stainless construction: High-strength alloy enables thinner, more efficient blades without sacrificing durability.
• Four-blade authority: Extra blade area improves bite in chop, reduces ventilation, and helps heavier rigs plane sooner.
• Stern lift & stability: Helps carry weight, maintain speed through turns, and hold plane at more comfortable RPM.
• Tunable launch: PVS venting (model-dependent) lets you fine-tune holeshot for your hull and load.
• Easy rigging: Compatible with Mercury Flo-Torq hub systems for streamlined installation and drivetrain protection.
