looking to prop my sc21
 
I currently have ny stock 4 blade prop on my sc21 with 5,0 liter. The boat currently runs 48mph at WOT and runs at 4800 rpm. I would like to get my top speed up to low 50's.

What pitch is your existing prop? I believe the operating range for your motor is 4400 - 4800rpms at WOT so you dont have much room to play with here.

Until we know what pitch prop you have on the boat now, there isn't much we can suggest.
