It ships with a Flo-Torq Reflex hub kit to help protect your drivetrain from common minor impacts and is engineered for use on a range of 25–40 hp Mercury and Mariner engines (see compatibility list below). Whether you're upgrading for better hole-shot, improved load handling, or increased responsiveness, this propeller is engineered to be a durable, serviceable option.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the Spitfire improve acceleration and handling?\u003c\/h3\u003e\n\n\u003cp\u003eThe Spitfire uses aggressive blade geometry to increase bite through the water, translating to quicker acceleration and firmer control when turning or punching through chop. Compared with many three-blade props, it delivers notably faster off-the-line response while retaining steadier handling at low-to-mid speeds.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e16–25% faster acceleration versus comparable three-blade props\u003c\/li\u003e\n  \u003cli\u003eFour-blade layout increases wetted surface for better grip in turns\u003c\/li\u003e\n  \u003cli\u003eOptimized blade rake and cupping balance top speed with control\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich engines and boats are compatible with this propeller?\u003c\/h3\u003e\n\n\u003cp\u003eThis Spitfire is intended for Mercury and Mariner outboards in the specified horsepower ranges and model years.
