HighAlititude Prop '04 wakesetter VLX

I have an '04 Malibu Wakesetter VLX that I bought a few months ago from a sea level owner. I live at Lake tahoe (altitude 6300 feet). I have the 340 Indmar Monsoon motor. Current prop is 13.5 dia x 17.5 pitch. I know i need to downsize my pitch especially, but does someone have a strong recommendation for prop size.

For reference:

'07 Malibu wakesetter vlx high altitude prop option from their website is a 14.5 dia x 14.25 pitch.

Dealer #1 phone call recommendation: 14 dia x 14 pitch

Dealer #2 phone call reommendation: 13.5 dia x 16 pitch.


Additionally, according to my perfect pass I'm topping out around 35mph right now - this seems rather low to me, wondering if it's most likely a prop issue or miscalibrated perfect pass. I know I should lose SOME top speed due to altitude but this sounds larger than I'd expect....

Thanks all...

Get the one that Malibu recommends from the website, it's the ACME 1235.

We had a new prop put on to make up for all the "extra" weight and top out at 37.

Good job that was quick. Hope it stays together for you, and have fun.
