Hi Richard,
I am slightly heavier and am using a 13x13. However, it is likely "over-pitched" since I can exceed max amps (100) with my current gear reduction (~2:1)
I am now debating moving to a higher reduction ratio - closer to 2.5:1 vs getting a lower-pitched prop. My understanding is being somewhat over-pitched means you get a little more speed in smooth water, but less "bollard pull" to tackle headwinds and such.
So I'm just hijacking your question and maybe we both get good advice :) (fwiw I already have the gear reduction, so prop route is more expensive)
