Here is another vid, this one still has the jet pump but he put a 260 racing merc powerhead in it

Wild ride but it sure looks like fun.

The owner says it is a handful though around 100

That's pretty wild. Never seen it before. Jet's are really inefficient, so the prop probably adds 10-15mph right out of the box. Wonder what the prop slip #'s are?

Look at what someone did with a single engine one down in SC.

Claims on Nitrous it will hit 100 so you have twice the motor and twice the fun with that one.

Can't see as how its going to be steerable. The speed at which the props will theoretically push it will be faster than the pump can move water with enough thrust, thusly, no steering. Needs rudders like the single one.

PS, tell him to make sure his life insurance policy is up to date

The ski ran 76 w/ a jet pump. After they put a prop on it w/ the same exact motor it went 104
