from my 2010 east cape caimen and 40 hp e tec power tech recomnded me the RED 3 13 1/4. Either 16 pitch for heavier loads or the 17 pitch for lighter loads.

Might be able to swing the same prop in a higher pitch. Call them up, they were very helpful.

Tried 10 props on my Generation 2 Copperhead with a 60HP Etec. 

THE BEST for my application is the ROGUE 4 blade 13 X 21

BEST HOLE SHOT
BEST TOP END
BEST FUEL ECONOMY
BEST CONTROL IN TURNS

COPPERHEAD IS:
16'4" hull weight is 360lbs 240lbs for the 60hp

Hope this helps
:D

Powertech recommended the red 3-blade prop also. Now just trying to figure out what pitch would be best.. I'm thinking the 17 pitch.

Sorry for the delay

WOT. Varied a lot. Between RPM and Speed

Viper 13 7/8 x17 was the first prop. It got great hole shot and about 40.1 mph but overreved my motor at 6250. 

Then tried 5 or 6 other props from a local used prop shop. Some were 3 some were 4 Blade.  Was getting good hole shot but couldn't get over 40 mph range was 36 to 37.8

Got the Viper 13 7/8 x19 was good hole shot but top end still wasn't over 40mph around 37mph. It ran about the same as the others I tried but brought down RPM to 5800 or so.

Told PIB and Poontoon about the Raker 13.5 x 20 and they are running those. Better bow lift and topend.

I never tried the Raker because I put a jackplate on and was blowing out. So I went to 4 blade. no blowout

Running the rogue 4 blade 13 x 21.

Difference from the viper 19
1 inch in diameter
Extra blade
2" of pitch
Able to move 4" on jackplate.  On jackplate
Runs fastest on 1" up 5700-5750 42.8 mph wot
Runs skinniest at 4" up tabbed down can run at 11mph still on plane

Hope this helps ;D

With the Raker 20 pitch, I'm getting 5600 rpm trimmed out; and 5800 when I'm running in a wwb chop trimmed out. I get 40-41 mph. No matter the load.
