Boat Speed

[BSF]

I will give it a try at a lower elevation, but I may not be able to get it out for a few weeks. Is it a common practice to change prop's when you go from a lower elev. to a higher elevation? I will have to call the dealer where I purchased the boat to see what he has to say. It would be nice if I could talk to the previous owner that had bought it new in 2003, to see if he knows what it could be.
