Welcome to iboats
You are only going up another 800 ft. What is your engines full throttle RPM range, 5000 - 5500? Unless you are currently running at or near the bottom of the range, I wouldn't be too concerned. If a the bottom end or lower, get a 19. Do you have a spare prop? I so, what is its pitch?

Edit: Were you using it to pull tubes and skiers at the lower altitude? How was its holeshot? Any problems pulling up the skiers?
