Original Prop for 1997 regal lsr

[Pwferd]

I have a 1997 regal 1900 lsr, what were the original prop specs for the boat. The motor was a 3.0L alpha one. The original owners manual list a 21p prop but no diameter. What is the best configuration for this boat?
Thanks Peter

Forget about the original prop. What is you max RPM with a normal load? What prop is on the boat now.? Do you plan on pulling a skier?
