One school of thought is for collision avoidance. Due to the right side having the right of way. The other has to do with torque created by the prop spinning to the right causing the left side to dip. By having the driver on the right it counterbalances it.
The only reason I know this is because my uncle worked for Burger Boat Company and I was curious myself.

My boat was built for a man. It steers from the motor.

But what side of the tiller handle do you sit on, the right or left?
Seats on the left so I steer with the left. But some days when I get wild I sit on the other and steer with the right. No judgment in my boat. Unless a steering wheel guy is in my spot
It is to counter balance the torque of the prop. the weight of the driver offsets the prop torque wanting to lift the starboard side of the boat. Made this way years ago before adjustable trim tab skeg was added to the outboard.
