Mercury Enertia ECO Stainless Steel Propeller 3-Blade 16 × 21 RH 8M0151259

The Mercury Enertia ECO 3-Blade Stainless Steel Propeller with part number 8M0151259 is designed for applications requiring higher top speed and efficient cruising. The 21-inch pitch is particularly suitable for high-performance boat-engine combinations where lower engine RPM at cruising speed, smooth operation, and optimized fuel efficiency are priorities.

The advanced Enertia ECO blade design specifically improves efficiency in the mid to upper RPM range without compromising acceleration or top speed. This achieves balanced handling with high fuel economy.

Made from Mercury X7 stainless steel, this propeller is around 30 percent stronger and up to four times more durable than conventional stainless steel propellers. The high material strength allows for thinner, hydrodynamically optimized blades with excellent shape retention even under heavy continuous load.

The Enertia ECO is approved for Joystick Piloting systems and can be used on both high-performance outboards and MerCruiser Z-drives.
