Michigan Wheel 31024 14.5 x 17 Aluminum 3-Blade Propeller for MerCruiser Alpha One/Bravo One, Yamaha and Mercury V6 Outboards

The Michigan Wheel 31024 is a 14.5 inch diameter, 17 inch pitch aluminum boat propeller built with a 3-blade design for outboard and sterndrive applications. It is cast from a high-grade aluminum alloy for strength that exceeds many original equipment props, and every Michigan Wheel prop uses a rubber hub bonded inside the barrel. That rubber hub is a sacrificial cushion: if the blades strike a submerged object, the hub can absorb and slip under the impact, helping shield the propeller shaft, lower unit gears, and motor from more expensive damage.

The 31024 is designed for trouble-free service and easy repairability, and it is backed by a Limited Lifetime Manufacturer's Warranty. It fits a wide range of V6 outboard and sterndrive powerheads, including Yamaha 150-200 HP and 175 HP V6 outboards, Mercury/Mariner V6 outboards from 135 HP up through 300 HP, and MerCruiser Alpha One, MerCruiser 1, and Bravo One sterndrives across multiple displacement and horsepower ratings. Because the 31024 is a direct-fit prop for these engine families, boat owners replacing a damaged or worn propeller can order by this part number without needing to match a dealer prop chart. Engine models built in 1997 and later require an additional aft washer (Michigan Wheel part 23395) not included with this propeller.
