I took a look at my jet in action w/o the cover and it seems to be on top of the water...I always thought they were supposed to be submerged so they kick the water out?

I did film it on my cell phone and posted it on youtube (after fixing housing)....

Anyone know if I should raise or lower my ride plate??? Or how it works when I do raise or lower it??? Holeshot vs. Speed....
