I have a max machine worx 2” thick billet top cap on my bravo xr with the larger mounting studs on my 713hp formula 271 spinning a left prop.

Run the LH prop, the boat was designed for it.
If it runs fine, why change? If it’s not broke, don’t fix it IMO.
I tested a RH prop on a single 29 and it would list to one side. I do know that the early 2000 low windshield style 27s came with a RH prop.

It’s has a 30rh on it now and that’s what it came with from the factory. I need less pitch when I loaded down with friends because it struggles to get on plane. My only concern is if I switch to a LH the stress will be in the other direction cause top cap issues or prop shaft stress. I don’t want to break anything when it can be prevented by getting a Rh 28 prop. I bought a LH not realizing it was a LH
