What is the proper prop for 4500ft elevation in Reno?

knowbody can tell me

Depends on the boat, engine, and use case. More details would help.

The prop is correct if it allows the engine to hit roughly 5,000 RPM wide open with your normal boat load of stuff.  If you surf, that might be 8 people and full ballast.  Whatever "normal" boating means to you.

Wakemakers is usually a good place to start.  According to their prop finder, you should be looking at a 2419 if you're planning to load up heavy to surf.  If just cruising around, 2247 might be fine.  What's on it now?  https://www.wakemakers.com/malibu-wakeboard-boat-propellers

Acme says 1615 for cruising, but agrees with Wakemakers on the 2419 if you're loading heavy.

2079 14.5 x 12 is on it now

the guy I bought it from also had extra prop 1939 14 x 15.5

That 2079 might be fine for your elevation.  2419 is the same pitch only 1/2" larger diameter.  That does make a difference, but unless you're planning to load up to the absolute max, might not be big enough difference to warrant the change.  I'd try what's on there first.
