With the trophy prop, were the vent holes plugged or wide open? If the holes were not plugged, that would explain the high ventilation on hole shot, and could potentially be an issue on full speed if the holes are so large as compared to your power band that the exhaust gasses might not be able to fully blow by the holes. If that happens to be the case, I might wager to say that is why you saw such high rpms and very slow speed.
The trophy prop is a great prop for overall lift along with bow trimming capabilities. Do you still have that prop to test more?
Also, where is the motor mounted on the transom? one hole up etc? Might be able to work with things there too... This sounds like it is one of those conundrums that can really challenge the mind.... We can find it, though...that I am sure of!!
