Key Metrics for Propeller Selection
Selecting the right propeller requires understanding the following parameters:
1. Blade Count (B)
Blade count refers to the number of blades on a propeller. In the table, we see both 3-blade and 4-blade propellers. Generally, 3-blade propellers offer higher top speed, while 4-blade propellers provide better acceleration and handling.
2. Diameter (D)
The diameter of the propeller is the width of the circle made by the rotating blades. The table shows diameters ranging from 12.5 inches to 14 inches, with variations based on specific engine models and propeller designs.
3. Pitch (P)
Pitch is the distance a propeller would move in one revolution if there were no slippage. In the table, pitch values range from 9 inches to 23 inches. A higher pitch propeller moves more distance per rotation, providing higher top speed but lower acceleration.
Common Propeller Part Numbers
The table lists both OEM part numbers and their corresponding SOLAS part numbers. Here’s a sample breakdown:
| OEM Part Number | SOLAS Part Number | Blade Count | Diameter (D) | Pitch (P) | Code |
| 6E5-45943-00-EL | / | 3 | 12 5/8 | 21 | K |
| / | 3411-130-21 | 3 | 12 3/4 | 21 | R |
| 6E5-45941-00-EL | 3411-130-19 | 3 | 13 | 19 | K |
