    prop change ? or gearcase change.

    My 22' apache scout w/300x is only pulling to about 5200 rpm's since i bought it. It was fine at first because i wanted to get a bunch of seat time before i really opened it up. I am running a 1.62 sportmaster and a 24p trophy plus 4 blade. I know the motor is rated up to 6700. I have checked the linkage and it is opening fully. Should i go down in prop pitch or change gear ratio. I know the sporty is not the right lower but i should still be able to get the rpm's up. Any thoughts?

    I ran into the same problem with a 25 trophy would hit my rev limiter at 6300 rpms with a 1.75. When I went to a 1.62 it would only turn 5200 also but the 1.62 wouldnt even get out of the hole with my 28 trophy. THe 1.75 turns the 28 5800 rpms. I would get the gears changed. JMO

    I actually want to switch from a sportmaster lower to a tourquemaster lower and change the gear ratio. I am told the sporty is slowing me down quite a bit.

    The previous owner of the boat did the same thing, had to get vent holes installed in the prop to get it out of the hole when he switched to the 1.62
