    Too many variables to get that right on the money. I would start with a 4blade Solas pitched to 15-23 with at least 1 1/2" at 23.

    15/23 was too much for my setup, i ran a 4 blade 15.5/22.5, and a skat 3 blade at 15.5/19.5 pitced by skat, it was right on with an 81mm nozzle at around 8400-8500 rpm. the extra .5 on the front dramatically helped my cavitation issue i was having

    Depends on how its bent. Also depends on what its going in too. RXP-X, RXP, Conversion are all different.

    i was running a 15 /23 -24... 4 blade....depending on temp ...and now i am on a 15 20 3 blade..on a 83 nozzle...granted it is now in full florida summer heat and humidity...

    3 blade are typically 3 mph slower...

    i dont really care for my 3 blade ...some love them ...IMO it is fine out of the hole...but when you hit is going 40 it doesnt pull like a 4 blade..and we ride alot of rivers the corner speeds are about 35 to 40 up to 70 75 on the short straights.....right where the 4 blade out performes the 3 blade.....i guess if you were racing bouies that slowed you downt to 15.20 then a 3 blade would be ok....as i said just my expierience..and opinion..

    the 4 blade was about 1-2 mph faster at the same rpm, but cavitation was alot worse. the 3 blade barely spun out of the hull and pulled alot harder to about 75 , from 75-85is is where you could feel the difference that the 4 blade made, i preferred the 3 blade because i didnt go 80 plus all that often.
