Yes you can. I would use it more for fine tuning that last little bit and not have a wide spread between the blades. If you have the correct number of blades on your motor you should be able to run the prop with the optimum pitch in it. That means if the blade performs best pitched at 10 degrees then all the blades should be set as close to 10 as the motor can stand. Example you don't want 3 at 12 degrees and three at 8 degrees. Another example you don't want a 6 blade that you have to run on 6 degrees you would be better with 5 blades set at 10 degrees

What do I do just remove two blades and leave the holders in there to take up the space?? Or do they make something to go in there?

There are a lot of 350's and a lot of opinions about pitch vs rpm. A reasonable starting point is 10°.

I ran a 350 DD with a 68 5 blade for years set about 7°. One blade less and a couple degrees is a decent guess knowing nothing about the motor. I preferred more pitch and WOT about 2800. A lot of guys target 3000. Just play with it till you find what it likes best.

The majic number for my was 2650, but I agree warp does better at less than 3000.
