Hey guys, I'll be going out with a buddy that just got a '19 20PHX with the 4 stroke Merc ProXS. Any guidelines on how far below pad these boats with this motor like to run at? I have a Ranger 520C that likes 2.25-2.5" below pad, but another friend with a 721 said his likes to run below 3" I thought. I realized the PHX is different. Any guidelines would be helpful!
