jet drives arent necessarily slow (some of those drag boats that do 100+mph have jets (full size boats tho) they just have a certian rpm where it cannot get water fast enough and just cavitates like theres no tomorrow.

sub drives arent good with rough water because although they have good grip, the props they use cavitate massivly if ever intoduced with air because they are full submerged when the boats on plane, unlike a surface drive, so when you junp a wave and the prop gets out of the water and then goes back in, its cavitates.......
100mph is good . but instead of a jet drive on the boat put a prop and you will see even faster top speeds.

actually subdrives are better in rough water.
