    I have an 07 2 stroke yamaha with a Power Tech which is great but at WOT it is only doing about 4900 rpms. the Boat is an 06 dolphin super skiff 16. # on prop is YM90PTR3R17p.

    Appreciate any advice :cool:

    Sounds like you want to up your rpms by about 400.
    that calls for a 2 inch reduction in pitch, You have a 17 inch pitch
    on it now, so  try a 15 inch pitch.
