Elevation and Boat Speed

[MSM1970]

You will loose 3% horse power per 1K feet elevation because of Ambiant Air Pressure, newer computer controlled engines change the air fuel mixture to make up for some but not all hp lose, thats why some boats cant hardly get on plane at lakes over 7k feet, if you go to Powel then to the berry. two different pitched props will give you best performance, most find a prop for 5 to 6k feet for lakes around here for all around performance, make sure you engine is running at rated RPMs wide open, high end of the range at Willard or UL then you should be good for Utah except Powel or SH. Then when you are at cruising speed you boat is at its best efficiency and is not as hard on your engine,
