1974 jet drive

i am curious, i know i have seen other jetboats like yahamas and seadoo's but they claim that their boats with jetdrives get up on plane as soon as you hit the throttle and i have seen these on the water and they do, but my question is if you had a jet drive v-20, would it plane as soon a you hit the throttle or is it the design of the hull?
