My boat is a 17' I/O with a 130 hp Volvo Aq130C and Volvo 270 outdrive

I have two props...a 14.25x17 and a 15x15...I use the 14.25x17 for sea
level and the other for high elevation (4000' and up) operation. These
props have always worked well when using them at the elevations
indicated.

Right now the low elevation prop (14.25x17) is installed and I was
thinking of just leaving it on for this weekend when I will be boating
at high elevation since I am pressed for time to change to the other
prop.

What will the general affects be of leaving the low elevation prop on
while I am boating at 4500' elevation?

Thanks!
