Important – Please Check Propeller Size
Please do not order by horsepower alone.
The same Yamaha outboard can use different propeller sizes and pitches depending on the boat, load and required performance.
Before purchasing, please check:
- Engine model
- Engine year
- Propeller diameter
- Propeller pitch
- Number of splines
- Existing propeller markings
- Original Yamaha part number
This Propeller Is:
9 1/4 x 10 J – 8 Spline
If you currently have a different pitch propeller, changing to a 10-pitch propeller can alter engine RPM and boat performance.
If the propeller looks the same as yours, this does not always mean it is the correct one for your outboard.
If you are unsure, please contact SSI Marine with your engine model, existing propeller size and spline count before purchasing.
