    Prop question

    I'm at about 3600 ft altitude. The Cobra I just bought had a 26p Trophy plus on a Mercury 225 efi. What should I set the jack at? And I have a 21p Tempest that did quite well on my other Cobra but it was a 200

    Thanks for the help

    You're probably going to have to play with it and see what happens, but I'd start at 3.5" PTP and go from there. At that altitude, the 26 might be a bit much, but the 21 won't be enough. Only way to really know is run it and see what happens. I run a 25 Trophy on my 180DC with a 175 at 3.5" and it's perfect. I'm also only at 750' above sea level.

    My favorite lake is at 5,700 ASL. I'm running a 23P Trophy Plus and it does really great. Awesome hole shot. I start at 4" below and go up 2" from there if I'm WOT. Low water pick up, the higher I go the more pressure I get. IDK if I'll ever get her dialed in as much as I move around elevation.
