    Altitude changes- is it worth changing impeller

    We live in northern utah. Just got a scarab 165 Id with the 1630 ace 300hp. We will run the boat in northern utah/ we have a house boat in lake powell during the summer but the boat will be ran in Havasu after lake powell challenge in September until dcb poker run in April. Is it worth changing...
