Just got my prop back from the shop.

Last summer while visiting with Todd he offered to run the numbers on my prop. I have long suspected that I should be seeing better performance under power especially when punching into a sea. Todd's figures showed that an additional 1.4" of pitch was optimum. The shop's Michigan Propeller program came up with numbers that were nearly identical. This is the initial analysis showing one blade to be 1/2" out of pitch to the others.
