Hello, I have recently installed a 300hp Yamaha Vmax sho 4 stroke on my 21' Sanger Alley Cat. I am looking for what is a good high speed and stable prop for a 21' Cat. I bought a 22" Bravo 1 prop for my all around prop, I had a 26" bravo 1 but it was very slow out of the hole with a full load. I am located in Denver Colorado so the Elevation is around 5500' for my local lake. I am planning a trip next month to head to a lake that is around 2000' in elevation. I would like some opinions on what prop I should look for to have some more top end speed and that work well with Tunnel hull boats.
