Prop for high altitude?

So we are moving to CO this summer. I have a 98 tige 2200v with about 300+ hp or so. No problems with power at sea level in WA state or down in Louisiana. We took it to bear lake one year and I cold not believe how gutless it was.

Short of buying a new boat or getting a bigger engine, what are my options? Specifically, what recommendations for a prop? We do an even mix of skating, wakeboarding, slalom and hydrofoiling. I ski at about 34 MPH.

Thanks
