Designed for both outboard and sterndrive powered boats, the Enertia is cast from Mercury’s X7 Alloy.
According to Mercury engineers, it’s four times more durable and 30 percent stronger than conventional stainless steel.
The stronger metal allows for a prop with thinner blades and higher rake angles,
which increases speed and fuel efficiency during acceleration and at top speeds. 
Enertia is available in 1-inch pitch increments from 14 to 22 inches in standard rotation.
And, counter-rotation models are available in 15, 17, 19 and 21 inch pitches.
