Default LH vs RH drive? Why single engine has LH drive?

I'm definitely not what you folks would call boat-savvy...but isn't a RH drive the "normal" drive for a single engine boat?

Why would a single-engine boat have a LH drive?
Or am I backwards in my thinking?

The only boats I know of with a single that use left hand rotation is Fountain and Profile.

The boat I'm going to look at tomorrow (Tues) is setup for a single-engine bbc and has a left-hand TRS drive.

It's an older hull (1980), but I don't know what year the TRS is.

Formula uses LH on their 271. Testing showed slightly better handling and minor top end gain. I have no idea why. No big deal either way.

I have seen a few 27-29 Fountains with a LH prop on single, one Baja 275, and just this week a Cobalt 220. All with single BBC and Bravo 1 LH.

Running it left hand helps counter the torque of the motor which sometimes makes the boat lean to one side when running.

The left hand TRS is stronger than the right hand due to the placement of the lower drive gear.

I've tried lh and rh on my velocity and didn't notice a difference except that I had to turn the wheel the other way to keep it on the pad. My guess is that maybe the owner blew a drive and just bought a LH drive, otherwise I'd have to go with Biggus. I don't think anyone ran a LH single in the 80's????
