Mercury Racing SpitFire X7 XP Propeller

Mercury SpitFire X7 XP Propeller

The Mercury Racing® SpitFire X7 XP propeller is engineered as the definitive four‑blade prop for Mercury 40-115 HP outboards. Built around Mercury’s proprietary X7 stainless‑steel alloy and finished with the precision-tuned Pro Finish, it combines a long, flared exhaust barrel and PVS vent holes with a custom blade‑thickness profile to deliver explosive hole shot, rock‑steady handling, and high‑rpm top‑end speed. While optimized for the Mercury Racing® 60R outboard, the SpitFire XP also suits any 40–115 HP Mercury outboard—allowing half‑inch pitch increments to dial in ideal wide‑open‑throttle RPMs.

Design & Construction

Four‑Blade, Long Flared Barrel & PVS Venting

• The SpitFire XP’s four‑blade geometry and extended, flared exhaust barrel “grip” the water, producing lightning‑fast hole shots crucial for shallow‑water runs and technical flats work.
• PVS (Performance Vent System) exhaust holes further enhance hole‑shot tuning, letting anglers fine‑tune ventilation to match engine height and hull load for optimal RPM response.

X7 Alloy & Precision Pro Finish

• Constructed from Mercury’s exclusive X7 stainless‑steel alloy—30 percent stronger and four times more durable than standard grade—this prop resists deformation under heavy loads and repeated impact.
• The Mercury Racing® Pro Finish is hand‑applied and includes perfectly matched cup heights plus a bespoke blade‑thickness profile for consistent, fine‑tuned performance across all four blades.

Performance Highlights

Lightning‑Fast Hole Shot & Shallow‑Water Running

• By pairing four aggressive blades with the long barrel design, the SpitFire XP accelerates through the water column in less than two seconds—crucial for punching through skinny‑water or surging onto plane with minimal throttle.
• Shallow‑water anglers benefit from reduced draft and improved stern lift, keeping the gearcase clear of submerged hazards while maintaining strong traction.

Exceptional Handling & Top‑End Speed

• Beyond explosive hole shots, the SpitFire XP’s cupped blade trailing edges “bite” into the water, stabilizing the boat in choppy conditions and reducing yaw—delivering predictably tight tracking at speed.
  
• Its refined Pro Finish and X7 alloy construction minimize vibration and drag, unlocking higher wide‑open‑throttle RPMs and up to a 1 mph top‑end increase over standard props on comparable engines.

Application & Tuning

Optimized for 60R & 40–115 HP Outboards

• Specifically matched to the Mercury Racing 60R outboard’s power curve, gear ratio, and lower unit design, the SpitFire XP exploits the engine’s full torque band for maximum acceleration.
• For general Mercury 40–115 hp outboards, its combination of four blades and PVS tuning offers a broad tuning window—ideal for a variety of hulls and load conditions.

Half‑Inch Pitch Increments for RPM Dial‑In

Available in 12″–21″ pitches, the SpitFire XP can be ordered in half‑inch steps, allowing anglers to precisely target their engine’s wide‑open‑throttle RPM sweet spot—ensuring both legal gearing and optimal performance.

Conclusion

For anyone running a Mercury Racing 60R or any 40–115 HP Mercury outboard in shallow water, tournament skiff, or bass‑boat applications, the SpitFire X7 XP is the go‑to prop for unmatched hole shot, handling, and top‑end speed. Its four‑blade design, long flared barrel, X7 alloy strength, and Pro Finish precision combine to deliver the lightning‑fast planing, rock‑steady tracking, and tunable RPM control that serious anglers demand—turning every run into a competitive advantage.
