[footinfool]

I have a 4 blade 13X16 on my Sport. What do different sizes do to your wake, hole shot, etc. What do the Air Nautiques use?? much difference between the nibrel and the stainless props?? Looking to get an extra to have on hand and need help on what to get??

Stainless blades are thinner

Judging by your callname I imagine top speed is a big consideration? I also barefoot and I run a 14x16 3 blade because I do not want to sacrafice top speed. I would recommend a 14x16 3 or 4 blade in stainless. The race boats use stainless because they are stronger and thinner thus more efficient. If you can have a good prop shop add a little extra cup it will work even better. You will lose a little holeshot.

ps this can be a very controversial subject...

Although stainless is stronger, I would go with the Nibral. The reason is that if you hit something in the water I would rather have the prop bend then the shaft bend. But as stated above, the stainless has other benefits.
