I'm about to lose it trying to set this unit up.
20' Ranger 491v with 2000 Yamaha vmax and Power Tech 22p prop. I've been from 1.75 to 3.50 below the pad and it's constantly porpoising at 22mph. I have an older jackplate with a 7" setback that takes me 45 minutes to adjust in my shop and cant adjust on the lake.
