    I purchased this boat last year and can not get more than 5200rpms and 50 mph with a tempest plus 21 pitch. Boat has been checked by Nitro dealer / mechanic everything is a-ok according to them. Is this all boat is capable of ? I thought boat should be capable of 54mph at 5600pm minimum. Any ideas? Thanks !!

    This doesn't necessarily address your concerns but does show there could be errors in the boat speedometers.
    A posting from last October: "The Nitro [my 2018 Z18, 150 4-stroke] speedometer was 3 mph faster at 60 than iPhone gps. 2 mph faster at 20. Although I don’t know the error on gps speed.
