    High + Dry Adventures Welcome to the family!

    Tried a few more props

    13.25 x 19 Rapture 3 blade cupped 36.5 mph at 5800rpm

    13.5 x 18 Raker 3 blade 36mph at 5900rpm

    Never tried a 3 blade with jackplate but is night and day with 4 blade vs 3 Blade
    3 blade had way more slip despite cupping

    13.25 x 18 4 blade Turbo worked well 38mph at 5750-5800 with better hole shot, but not as good top end as the 13 x 21 Rogue 4 blade 40.5 mph at 5400-5500rpm.  The Rogue runs lower RPM though.  There is always give and take with these props

    Do I want top end?
    Hole shot?

    Going to try the 13.25 x 20 turbo might just dial it in! 

    Still have the Rogue 13 x 17 for heavier loads and sick hole shot.

    We shall see.

    My skiff is about exactly where yours is.
    I run the 17 for heavy loads
    But my fastest prop so far is an old style omc sst that my prop guy cut down to a 12 3/4 x21.
    Still get up quick, a lot more bowlift than the 17 tho but hauls the mail.
    And has a very efficient cruise of (gps both ways) 25-26mph at 3000 rpm.

    Fastest ive gotten it so far was 47mph (gps) at 5850rpm
    Very light load.
    Since then ive gone up two more holes on the mounting bracket

    Thanks for posting your numbers. I have a 19 & 21p Rogue to try with my 60 E-Tec soon. I'll post my findings as soon as I can.
