Description
Forget what you think you know about four-blade props. The aluminum Mercury SpitFire was engineered to excel. It provides the handling you’d expect from a four-blade, with speeds that rival a three-blade.
- Aggressive blade geometry enhances handling and top speed, while contributing to 16-25% faster acceleration than a comparable three-blade prop
- Patented Mercalloy aluminum alloy is engineered specifically for crafting props that are strong, yet ductile enough to handle minor impacts
- See your engine owner's manual for the thrust washers and prop nut part numbers to best fit your engine or drive with this propeller
- Mercury parts and accessories are backed by decades of experience in engineering, testing and manufacturing to provide the best fit, function and performance
The SpitFire Advantage
Flo-Torq Hub Kits
Zero Compromises
Thanks to the most aggressive geometry of any aluminum prop in its class, the SpitFire delivers exceptional overall performance, including high top speeds, confident control in turns and 16 to 25% faster acceleration than a comparable three-blade prop.
No Ordinary Alloy. No Ordinary Prop.
Mercury leaves nothing up to chance when casting SpitFire props. We make them from patented Mercalloy® material, which allows us to cast prop blades that are thin, yet durable. Thinner blades create less drag, for a higher level of performance.
