The SpitFire advantages

Flo-Torq hub kits

Mercury Flo-Torq® II hub kits are proven to be reliable across a range of applications. For Mercury 40hp CT engines and higher, you can upgrade to the Flo-Torq SSR for smoother, quieter shifting.

Zero compromises

Thanks to the most aggressive geometry of any aluminium 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.
