Michigan Wheel 31066 Aluminum 3-Blade Propeller, 14-3/8 x 21 Pitch, Left Hand Rotation, Cupped, Replaces 58130-ZY3-021A

The Michigan Wheel 31066 is a 3-blade aluminum outboard propeller built for boaters who need a left-hand (counter) rotation prop for twin-engine or counter-rotating outboard setups. Measuring 14-3/8 inches in diameter with a 21 inch pitch, this propeller uses a cupped blade design, which helps hold the stern down, improves bow lift at speed, and reduces ventilation in turns or rough water compared to a flat-blade design of the same size. Aluminum construction keeps the propeller lightweight and affordable while still standing up to regular outboard use.

The Michigan Wheel 31066 cross-references to OEM part number 58130-ZY3-021A, making it a direct replacement option for boaters replacing a damaged, worn, or missing counter-rotation propeller. At 8.2 pounds, it ships ready to install using your existing propeller hardware (prop nut, washer, cotter pin, and hub kit are not included). Because this is specifically the left-hand rotation propeller, it is not interchangeable with a standard right-hand rotation prop of the same diameter and pitch; a right-hand version is a separate part number.
