My suspicion is that they have been keeping you "bow-down" when at speed. When you remove them, go out some nice flat day and open her up. Then trim the engine out until it ventilates (blows out/overrevs) then trim back in until it bites. That is your best speed with that prop.
My previous RIB was a year 2000 6.5m Stormforce - nice boat.
Yes my bow is down, well at least compared to my last rib, a 7 meter ribtec that had an inboard diesel, wow that thing was heavy at the back.. Yes I'm growing very fond of my Stormforce, softer ride than the bigger ribtec too which was a surprise.
Fingers crossed this "nice flat day" isn't too far away!!
I will let you know how I get on.
