How do i determine the right propeller?

I have a Johnson VRO 90 HP, model number J90TLESB. It is on a 24" pontoon, an Aqua Patio AP240. How can I determine the correct propeller to put on this engine?

Here’s a great place to start. http://www.marineengine.com/parts/solas-propeller/

you should have your max RPM between 5,000 to 5,500 with a normal load in the boat.

thanks... looks like 14x13 is my prop. Appreciate it!
