Choosing the Right Pitch
Pitch is the most important propeller specification. Selecting the correct pitch ensures your engine reaches its recommended wide-open throttle (WOT) RPM range, which for DF9.9/DF15/DF20 engines is 5,000–6,000 RPM.
|
Scenario |
Recommended Action |
|
Engine over-revs above 6,000 RPM at WOT |
Increase pitch by 1" to 2" |
|
Engine under-revs below 5,000 RPM at WOT |
Decrease pitch by 1" to 2" |
|
Heavy boat or frequent passengers/gear |
Start with lower pitch (9"-11") |
|
Light hull, solo rider, speed priority |
Start with higher pitch (13"-15") |
|
Shallow water / weed-heavy environment |
Consider smaller diameter / lower pitch |

For most DF9.9/DF15/DF20 owners; fishing aluminum boats, inflatables, tender use; the OEM aluminum prop is the correct and most cost-effective choice. Stainless makes sense if you are pushing performance limits or in prop-strike-free deep water.
