    Prop update / recommendation

    Motor: 1993 Johnson 90hp
    Boat: Skeeter ss90 16.2ft

    First prop: aluminum 3 blade 13.25x19 (5400 rpm and 45.2 mph)
    Second prop: SS Powertech 4 blade 13.25x17 (5200 rpm and 43 mph)
    Current prop: Ballistic 3 blade 13.5x17 6000-6100 rpm and 44.5 mph)

    Can I have my current prop worked enough to bring rpms back in range? Or close, because these tests were by myself.

    Motor is rated for 4500-5500rpm.

    I'd like to make the current prop work. I love the way the boat responds to this one.

    No... You cant get 600 less rpms from that prop. The cost of that is close to getting a good used 18P Raker V4 would not be much more anyway.... I think you are leaving some performance on the table.
