Almost all gas engines want a little leaner fuel mixture at high altitudes. I used to have an old 50's vintage Johnson 5 hp. that I had to lean out quite a bit to get it to run decent at Fish Lake. Another thing I learned about running an outboard at Fish Lake is that you need to run the next step hotter plug, especially if you are trolling. Dunno about the newer outboards but the old ones don't have a thermostat & that cold water at Fish Lake wouldn't let the engine run warm enough to keep from fouling the plugs.
