Hey guys I just got my first longtail. Was wondering what happens when you bend the plate above the prop up instead of down as well as down instead of up. Kinda just want to know how you can tell you got it in the sweet spot.

Bend the cav. plate up and you will push the prop down in the water. Bend the cav. plate down to bring the prop up. Make sure you have the right motor for your transom height. MB uses a longer shaft for a tall tramsom and I think GD uses the same length shaft but changed the angle of the cav.plate to make the compensation.
