  • Equipped with Flo-Torq II hub kit 835257K1
    The Alpha 4 propeller is an outstanding prop for runabouts as well as daycruisers. Four-blade propeller performance at an aluminum price. Bolt this prop on and your boat should get on plane quicker and stay on plane at lower speed that with a comparable 3-blade propeller but sacrifice some top end speed loss. Great watersports prop!

  • Mercury recommends the 4-blade SpitFire propeller as the aluminum option for 90 CT - 150 outboards and Sterndrive applications. When transitioning to a SpitFire, increase 1" of pitch from the Alpha 4.
