I tried asking this by attaching to an older thread, But I thought I would start a new thread and ask here.
I am running a 21 pitch prop at 5950 rpm and 46.3 MPH.
If you use 2.0 gear ratio thats a slip of 21%
I read in another thread where Huey Posted Model# A115SHLAF has a 2.36 gear ratio
I was wondering if that would be the same for the graphite engine?
This would make my prop slip 8% which would be great. My dealer is shocked I can run a 21 pitch. His literature says 2.0 gears also.

Look on the serial number tag on the motor for the complete model number, there is one more letter needed. If the final letter is " B " or higher, then you have the 11:26 - 0.42 - 2.36:1 gear ratio.
Ask your dealer to refer to service bulletin dated January 2014, number 2014-01(S)
