Mercury Spitfire Propeller – 14 x 23 RH – 8M0084497
Upgrade your boat’s acceleration and handling with the Mercury Spitfire 4-Blade Aluminum Propeller 8M0084497. Designed with advanced blade geometry, this performance propeller delivers the quick hole-shot and superior grip of a four-blade prop while maintaining the top-end speed typically associated with three-blade designs.
Built from Mercury’s durable Mercalloy aluminum alloy, the Spitfire propeller is engineered to withstand marine impacts while maintaining strength and performance. Its aggressive blade design improves acceleration and control, making it ideal for heavier boats, towing applications, and high-horsepower outboards.

-
Get on plane faster

Maintain grip in tight turns
-
Improve mid-range acceleration
-
Maintain stable performance in rough water
This makes it a popular upgrade for watersports, heavier boats, and performance-oriented setups.
Important Compatibility Note
