Enertia, a revolutionary product that will measurably improve acceleration and top speed on many heavy deep vee boats powered by high-horsepower outboards. Enertia has also been proven to increase the overall performance of runabouts and pontoons. The Enertia is the first propeller to utilize the added strength and durability of the new X7 alloy. This patented new alloy allowed Mercury's Propeller Engineers to develop a propeller design that far surpasses the limits of conventional stainless steel. The X7 allow is 30% stronger and 4 times more durable than conventional stainless steel. Typical benefits of this new design include:

• Better Acceleration and top end speed
• Thin blades and higher rake angles for increased efficiency
• Stays hooked up; fewer blow outs while cornering
• Keeps boats on plane at slower speeds
• Enertia is avialable in one inch pitch increments to dial in the ultimate performance of todays high horspeower outboards.
• Equiped with Flo-Torq II Hub Kit 835257K 1
• Equipped with PVS - Performance Vent System solid fittings.
