Which Hull? - 91 XP vs 94 SP

[NoRdO]

Hey Folks,

I have four hulls and three motors....

Hulls:

-91 XP
-91 SP
-94 SP
-94 SP (parts ski)

Motors:

-587 white single carb
-587 yellow twin carb
-657x

Which engine should I put in what ski? Is there any advantage to the later hull? The 91' hull seems to be about 15lbs lighter than the 94'. I bet the 91' hull would really rip with the 657x.

The 94 hulls have sponsons, the 91 hulls don't. I was thinking I could swap the sponsons from a 94 hull to the the 91 xp along with the 657x motor and electronics...

Thoughts? Pumps are out of all hulls at the moment.... so I will pitch accordingly

I have heard the sp hull with a 720 is a hoot. Ridden a 90 xp with a 720 with factory pipe and 800 carbs? That was something else. My next project will be an sp with a 720.

91 sp or 94 sp? Is one hull better for top speed/acceleration, or handling?

I have both hulls, would love to build a ski for top speed and one for handling... I would think the earlier hull would have better top speed and acceleration due to weight differences but I'm no expert...

I personally would pick the 91. Because it would be sketchier at higher than originally designed speeds which could equate to more fun. Hehe!

I think the 94 would handle speed/track better, but neither are really designed to go that fast. The 91 is a bit lighter and would spin out more. I've always wanted to ride one with a 720. My buddy had a 95SP with the 587. It was slow and underpowered, but it was so easy to do 360's on it If you've never done it, just get on plane, build up some speed (top speed on 587) and cut the wheel. Hang on, as it'll try and throw you
