I have h56 with a mercury 150Xr6 sitting on a 8" jack plate with a tempest 23p that's been balanced and blue printed with cup added. It is right at 3" from bottom of pad turning 5600 to 5700 running 65 on gps, water pressure is at 15. I can trim all the way up and it doesn't throw a rooster tail or try to blow out. Do i need to raise it up more to get rpms up and where i don't have to trim all the way up. Any help would be greatly appreciated!!!
