Hey guys, we have a 7EC with a C-90-12 and a sensenich 76AK-2-48. I was wondering what is approved for a climb prop, or could we re pitch the obese have. We are only seeing 2200-2300 on takeoff

Note: use a reliable tac, not the one in the dash to verify the existing rpm!
Where can i find a "localish" prop shop in new england?
Clint what are you running on your 90, I like the way you try all this stuff. dougNot sure if this will help or not, but in a conversation with Craig Catto, he told me that his 76x36 on a c-90 @2200-2300 was outpulling the whirlwind ground adjustable even when it was set to give a static rpm of 2600. Then there are the guys that run thier o-200s up to and over 3000 rpm and swear that thats the way to go. All experimental of course...
I have been doing some reading, sounds like 42 pitch is about right, Can a prop shop re pitch a 48 to 42? Where can i find a "localish" prop shop in new england?
My C85 stroker has a C90 cam, 85 pistons 8.6-1 and would not turn a catto 7636 above 2250 static. I never flew it on my J4 because it couldn't get me off the pond that my Mac 7440 does.
