Superior acceleration generated through its smaller diameter design
Faster acceleration than three-blade props to get on plane faster
Added cup provides superior holding in turns and heavy seas
High rake blade design for higher speeds
Spitfire X7 propellers have forward exhaust ventilation holes equipped with the PVS (Performance Vent System) plugs. The size of the hole in the PVS are used to vary hole shot engine RPM's and acceleration to best match the boat and boating application. See your owner's manual for the Flo-Torq hub, thrust washers and prop nut part numbers to best fit your engine or drive with this propeller.
Like the aluminum Spitfire, the stainless steel Spitfire X7's small diameter generates unmatched acceleration while the aggressive blade design and cup create exceptional speed and holding.
If RPM is appropriate with a current 3-blade propeller, replace with the same pitch.
