24ft Carrera Classic, 454 w/ Bravo 1 1.50:1 gearing. Ran it with a 26" 4 blade prop and couldn't spin above 3200rpm. Took it out yesterday with the 23", 3 blade and it spun right around 4800rpm. Now my question.

I want to be able to get out of the whole with a few riders and am looking to have a spare prop too.

1- Should I go with a 21 or 22 pitch 4 blade, stick with a 23 or even try a 24 pitch 4 blade?

2- Would a 4 blade perform better than the 3 blade?

4 blade 26 is for sale too since I won't be using it. I'll post it in spam later
