The 12.5 x 12 prop is for the 1:1 trans. The factory powerslot prop is 13.7 x 17. The fact that you have less pitch and less WOT rpm confuses me. I would think that you would be banging your head on the rev limiter with that prop.
Check the ratio on your transmission tag. A 13.7 x 15 .80 is used with the 1.26:1 transmission. I know absolutely nothing about the TT boats.
