Copperhead Gen 2 with 60HP Etec and Jackplate

    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.

    First, yes I realize the thread is 3 years old.

    I am looking to change my banged up prop on a 60 etec and while looking at the 13.25 x 18 4 blade Turbo mentioned above, it is shown as a yamaha prop. Is this a problem?

    If the original poster or anyone else has any idea I would really appreciate the insight.

    You mean 5 years? Couldn't help but bust on you. Sorry no info on the prop but @paint it black is pretty experienced with etecs and props on copperheads.

    lmao!! too funny

    currently running a 15p 4 blade rogue, perfect RPMs but looking for more top end and less focus on holeshot.

    Wondering if the same pitch prop, but a 3 blade viper will keep me in same RPM range, as a second question.

    I had the best results on my copperhead spinning a 20 pitch Raker. It's what I am also spinning on my Salt Marsh Heron with the 60 Etec and have gotten the best results from it.

    And I personally drove Ryan's Copperhead (High & Dry - the original poster of this thread) and my Copperhead had much better hole shot, and overall performance with the Raker than he did with whatever the prop he was running was.

    The 20 pitch Raker gave me 5600-5800 RPM's on the Copperhead, with top speeds regularly in the 39-41 range. Hitting a highest speed of 42-43mph on the right situation.

    My Heron does 5800-6000 rpm's, doing 38MPH WOT, and I've seen ~40.7 mph in the right situations.
