for those that also have the same question here comes some more info
port (Passenger) and starboard (Driver) side boom placement
is there a specific reason a boom is placed on either the passenger side or drivers side ? YES - and well no
a few pros and cons:
that's how the previous owner had it installed
that's how my friend installed it
That's how I installed it on the last XX boats I've owned
but WHY



?
passenger side - typically most common:
1- because that's how everyone else installs it
2- easiest for passengers to take pics of the skier on the boom
3- easiest for the instructor to shout to the skier (provided instructor is not the driver)
4- unobstructed path from pylon to gunnel - some boats the drivers seat is in the way
5- typical 1:1 direct drive naturally pull starboard so driving with the boom on port requires slightly less correction
6- counter balancing the the skier and boom weight is easier
Drivers side - preferred by most footers / footer drivers / footer instructors
1 - allows driver to have his eyes on the skier @ all times, even when picking up a downed skier
2- if driver is the instructor - he doesn't have to shout as loud
3- some starts (back deep) require specific throttle @ specific time which is easier to do when boom is on drivers side
boat driving with a boom installed and skier in tow is really a different animal and the boat will react differently still depending on which side it is installed - consider a few of the points above (and a few more Eddie might add

b4 you install your boom
my preferred boom rig
Barefoot International straight boom (unless long windshield wings require a contour boom, or if installing drivers side and drivers seat is in the way)
BI boom height adjuster
BI boom extension
tie down strap from boom gunnel pad to rear transom eye
