      Is it the same prop as the 1953-1954 15 hp motors?

        The Evinrude chart shows 9×11 for those up to 1956. (Strange that the Johnson chart shows 9×10 for 1956). I guess 9×11 would be ok with a real light rig. I think for an average or heavier load you’d get closer to max. rpm’s with a 9×10 and I think I’ve even seen 9×9 suggested on some charts.
