Enertia Eco (16 x 23") Mercury RH Propeller, 48-8M0151263
The Enertia Eco propeller was created with an innovative design specifically to provide optimal fuel economy and performance at cruising speed – the engine rpm range where boaters spend most of their time. It features a broad 16-inch diameter design, with an extra-large blade area and a high progressive rake for increased bow lift.
Compared with some popular propellers used for similar applications, the Enertia Eco prop can provide up to a 10% improvement in fuel economy at cruise and significant improvements across the rpm range. It’s built with proprietary Mercury X7 Alloy, which is 30% stronger and four times more durable than conventional stainless steel.
- Hub kit is sold separately. Please see the fitment information provided to select the correct hub kit for your application.
- Enabled with 3-hole Performance Vent System (PVS) to allow optimal hole-shot customization.
- Mercury engineered the Enertia ECO prop to squeeze every last mpg out of high-horsepower engines. Its extra blade area and aggressive design efficiently transfer power to the water at cruising speeds, reducing fuel burn in the rpm range where boaters operate most of the time.

Testimonials

Isaiah C.
Mercury Enertia Eco Propeller
I installed the Enertia Eco propellers on my Regulator 33 Center Console and the fuel consumption improved considerably over the Revolution 4 propellers I had.

Capt. Roger K.
Grady-White Fisherman with Enertia Eco Prop
We make a few long runs to the Bahamas each year, and other long trips too. The Enertia Eco propellers help with the fuel economy, and they handle well too.

Rodney B.
Enertia Eco Prop
According to the SmartCraft Mobile app we got significantly better fuel economy., roughly 10%. The props will be for themselves if we do enough boating. Hopefully we do!

Luther B.
Enertia Eco Propeller on Boston Whaler
We have a Boston Whaler Outrage that we consistently take off-shore. What pleasantly surprised me about the Enertia Eco propeller was not only the fuel economy but also the handling in rough waters.

Jenny M.
Mercury Enertia Eco Propeller Fuel Savings
My cruising speed is at lower RPMs now, so I'm not burning as much fuel. The extra bit of bow lift really helps. Thank you!

Larry J.
Enertia Eco
The propellers arrived in time for out trip. We ended up getting them installed before we left and kept the Rev 4's as spare. I didn't measure the fuel savings, but the handling and speed was good.

Ace G.
Enertia Eco Propeller Fuel Economy
Making the long runs we usually burn through nearly a whole tank. We made it there and then some with Enertia Eco.

Whether you’re looking for a replacement prop or want to optimize your boat’s speed, hole shot or efficiency, keep in mind that prop selection is about more than just pitch, diameter and number of blades. Performance is influenced by every aspect of a prop’s geometry, right down to cup, rake angle and edge shape.
