I am starting a build on a Copperhead soon, and want to go with a 40 HP Yamaha. Can anyone give me suggestions on how to prop it? Thanks!

It all depends on your preference. You gotta establish if you want more whole shot or top end? I have a 14 pitch SS on mine and it jumps out of the water like a wet cat! But then like PIB's it takes a little longer out of the hole but has more top end with his 20 pitch. So establish whats the best for your conditions and make you decision from there.

Thanks for the replies. It will be a center console, and if I had to choose I would lean toward better hole shot. But a good balance of hole shot and top end would be my preference. I really don't know much about pitch and how it affects performance, so I am grateful for anything you can tell me.

I run a 50 2 stroke yamaha. I have a 14 pitch stainless. It has a excellent holeshot. My top end is about 36mph. If I raise my pitch to about a 16 I could probably gain a few more miles an hour in my top end but then again my hole shot will decrease. If your fishing very shallow water you might want a better holshot to get up and go. Or if you run more open water you could run a bigger pitch for a better cruising speed. It's really your preference. Just decide what your going to mostly do and decide from there.

Thanks! I think maybe a 14 pitch will work. I'm not that concerned with top end speed, as long as I can get to the fish and get back out when the tide drops.

I am definitely going with a Yamaha. I have nothing against the other brands, it's just that I have always had Yamahas and they have never let me down. Gonna go with what I know.
