Look on the outer hub of the prop near the blades or inside the hub. Most props are stamped with a series of numbers. Pitch is always the last number listed. Example: 3 x 16 x 24.5R 3 - Number of Blades (occasionally displayed) 16 - Diameter 24.5 - Pitch R - Direction of Rotation (R = Right/Standard, L = Left/Counter) |
Pitch is stamped on the outer prop hub...

...oraround the inner hub. |
Props spin either clockwise (standard or right-hand rotation) or counter-clockwise (counter or left-hand rotation).
Most single engines use a standard rotation prop. Most twin engines use one of each.
To determine what prop rotation you have, look at your prop as if on a boat. Position a blade pointing straight up. If the right-hand side of the blade is closer to the boat than to you, it's a standard rotation prop.

Props are often stamped with both dimensions and a part number. Look on the outer hub of the prop near the blades or inside the hub. Numbers similar to 15 x 17 are the prop dimensions (diameter & pitch). Those numbers are not your part number! Part numbers resemble 031018, 48-11320A40, 2231-103-12, etc. |
Look around the inner hub or on the blades.

15 1/2x17 is not the propeller part number!

Volvo Penta DuoProps have a front and rear propeller that rotate back to back on the same drive. The front propeller is closest to the boat and hits the water first.
DuoProps have both a counter and standard rotation prop to eliminate steering torque. The front prop is always counter rotation. The rear prop is always standard rotation.
Volvo Penta DuoProps are each stamped with a size code (D2, F5, T9, etc) that is used to find a prop replacement. With this code you can replace either the front or rear pieces, or the complete DuoProp.
