need prop help

[readytoboard]

I have a 2007 RZ2 and want some feedback as to what the best prop and pitch is. I currently have the factory 14.25 x 14.
I am thinking about putting on an ambush 14 x 18. Is this wise or not and if not what has somebody used that works great.

What's your altitude? Tiges typically come with the ACME 537 (13.5x16).

Sounds like you've got a good choice on there.........call the folk at ACME Marine and get their rec to be sure.
