    Hey guys i"m new to flatbottoms. took mine out for the time time this weekend. I notice that the front for the boast starts porpoising / hopping around 50mph making it really hard to stay in the throttle. hitting the down pedal seams to help but i can't press it down fare enough to smooth it...

    I have an open bow jet boat. When you put the diverted up to throw a rooster tail the boat porpoises really bad. Any ideas? Thanks in advance, Dick

    I just took out my boat after installing a Hyd PD w/ wedge on my boat and it is faster by 8 mph but squirley and porpoises pretty badly. It is a 21 Omega Open Bow with jacuzzi.

I didn't have the balls to try and power...

    I was hoping that someone could give me some insight on why my boat porposes so bad, and naturally a reasonable way to fix it. Boat is '94 20' Carrera Eclipse with Chevy 502, American Turbine with a diverter. At a 45mph plus speed the boat sits and handles well no problems. The family likes to...
