Oddball stuff: your catching Air and flopping up and down. Is it worse with a headwind?
your pulling angle on the step and just not enough hull in the water to hold it up.

Kinda guessing fastest we have here runs 50 55 fine not a playcraft.
I think that air bleeding is my problem. It compresses at speed and has no where to go but out the back. Because of the engine being heavy and setback the air escape route is very limited. I have tried a 4-blade to give me more stern lift, but it only helps just so much and the porpoising continues.
