I've read some where that you lose 3% HP for every 1000 feet of elevation gain from sea level. Also you may need to adjust your fuel to air mixture, it is probably running rich at that altitude. Prop change is the easiest to do.
My 25 HP merc ran like crap for the first bit at strawberry then cleaned up and ran ok, I don't know if it has a self adjusting mixture or what the deal was. Then when I got back to Cache valley it ran poorly then cleaned up again.
