Prop for 2003 20V

[mudhen]

I have a 2003 20V and do a lot of surfing and slalom skiing. What prop are you running? How many blades, 3 or 4?

Currently I'm running a 3 blade, 911 10x13 and I'm having some issues with it spinning out. It is supposed to provide better hole shot and power for surfing. However it is starting to spin out occasionally because it doesn't have a lot of cupping. I also have the 515 13x12 as a spare. I'm debating moving to a four blade and want to see what other people are doing. I really want to protect the ski wake. In talking with a prop place in town, they think I can get away with a 14" prop. Thoughts?

Thank you in advance!

If you've got the black 1:1 v-drive, it will not like spinning 14" 4-blade. Need to stick with a 3-blade for surfing. Im surprised you are experiencing cavitation from the 911. Are you running with a high degree of list or a ton of aft weight? Any dings in the prop?

Thank you. The prop doesn't have any dings, that was my first thought. The cavitation happens when I am not loaded with weight. Even if it is just me in the boat (175lbs).
