2016 721 new motor location

[Tjflickshake]

I have a 2016 721 with a 10in atlas plate. It has a 2stroke Merc Pro Xs and I upgraded and bought a new Four stroke. What hole on the motor is it mounted on the plate. My deal doesn’t deal with many bass boats so I wanna tell them where to put it

Here's my 2015 721 with a 2020 Mercury 250 pro xs 4 stroke mounted to an Atlas 10" Hyd. Jackplate. I just added The Leash but am sure it's mounted to the 2nd hole down. Top and bottom pictures of port side for reference.IMG_20240122_195340839.jpgIMG_20240122_195308238.jpg
