Which mounting hole on the motor should you use to mount the motor to the jack plate. Jack plate is a manual Hydro Dynamics 6" Champion plate, or does it mater which mounting hole you use. Boat is a 95' Champion 186 SCX motor is a 2010 Mercury 175 ProXS. Original motor was 175EFI mounted on transom from the mfg. Dealer that installed new motor mounted it in center hole.
