Location: north central wisconsin | I can see that in a high powered or perfectly matched rig, but, in an underpowered rig, wouldn't a bit of flex in a prop with too high of a pitch, allow for it to spin faster resulting in a better hole shot than a steel prop in the same pitch? Sure seems to be the case with my big boat and my little one where the same pitch al props get me up and out quicker but less top end. Isn't there a curve of sorts depending on horesepower/transfer of power potential? I always thought the lighter props spinned easier out of the hole but flexed more on top and didn't hold their form for full speed potential. Good to know that isn't the case, but I would like to know why the higher pitch aluminums always out-rev the stainless, at least the ones we've tested..
Here's a dumb question: why does my 16P stainless have better top end, and slightly less hole shot than the same aluminum. My prop guy told me a good rule of thumb is that the same pitch alum equals about 2 less in the same stainless for my motor. He said because of weight and flex. Is it just the weight then? Wouldn't flex cause the diameter to go down a bit, making it easier to spin? Great thread, great info.
