Looking at box stock props, the Trophy is a good but the Pro Max should offer better overall performance and durability. The 8″ jack plate might offer a little better performance when you marry with the right prop. I think the Pro Max, with its tremendous cup wrapped around the blade tips, will give you what you’re looking for with the set back. The Trophy is ″ in diameter. The Pro Max is ″. The props share the same hub size. The Pro Max doesn’t have vent holes nor does it need them. There’s enough exhaust venting over the small hub. The plastic blow out ring fitted over the front of the Trophy would hurt the Pro Max’s planing performance. I think the Pro Max would be a fun prop for your set up.
For PROP testing, we either used a series of dilutions of PROP in water, which you sip then spit out, or we use filter papers which have been soaked in PROP and then dried. You placed the filter paper on your tongue. Then you rated the intensity of the taste. For this rating we use a line marked with words at quasi-logarithmic intervals (the Greene Scale), going from "Barely Detectable" to "Strongest Imaginable." We then measure these intensity ratings using a scale that runs from 0 to 100; the higher the rating the more sensitive you are. These ratings allowed us to classify people according to taster type.
