Left handed prop on single engine❗️❗️❗️

Hey guys, I have a 27’ fountain fever with a single blue 500 efi with a left handed prop, is this set up right for this boat? She seems to run fine! 74mph top speed.
Thanks!!

Fountains came stock with the left handed prop, I believe. The plus side is used LH props are typically cheaper.

Most formula and fountain single engine boats run a left hand prop. Jeff Wurl

A left handed prop is to offset a "torque lean" typically.

Talked to Tom at Hydro-Motive and he recommends LH props for single drives to offset torque from the motor. From what I understand though LH props put a load on the Cap which is weaker, hence why I stick with the RH prop and deal with the torque.

Yup, I put a LH prop on my previous boat after running RH for around 150 hours. After 2 short runs my drive broke a stud off the top cap and exploded.

So I have been running a 30p right hand on my 27 Fountain with X drive and just purchased a left 28p due to always having a full boat of people. My issues now after reading this is should just buy a RH and not risk breaking anything. I know the bravo can spin either direction but I was also thinking after running on one set of gears for 240hr it wouldn’t hurt to use the other set to balance wear? Any more thought on this before I try the 28p or should I just sell it and get a RH

many singles have used LH props

challenger was another one to add to the list

to be funny many single engine twin prop outdrives have a left hander to

I ran a LH prop on my last 2 Advantage singles with no issues. I did install billet top caps with 7/16 studs though

Thank for the info everyone, at this point I think I’m just going to sell the LH 28 and look for a right.

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
