300/440/550 440/650 conversion ski with AM bottom hull?

[superjetguy]

hey guys i just bought a js440 with a 94 650sx engine in it. the ski was sitting on this guys side yard for 10 years without being ran. i put gas in it and she fired right up. my question is did anyone make an aftermarket bottom for these hulls? ill post up some pics but its wider, and about 3" longer.

That's wild looking, maybe early superjet bottom conversion? Or possibly 750.

There was a company that made a bottom kit that you basically glued to the bottom of your existing hull. Think the name was venture hulls or something similar.

Venture waterwerks is on the ride plate.

I think Rob Flores use to race on a modded ski with one of these hull bottoms.

I was close!

It will be running this weekend. I'll ride it and let everyone know how it handles. Ps. It's for sale .. Hah

 

[superjetguy]

So I thought I'd update I rode the ski it handles great! A little cool thing I found out is the ride plate fits a superjet also.

guys!!! i need help, the ski feels underpropped or something. it has a skat 14/17 is that fine for the 650 or should i get another one? i have a skat 15.5 prop but i dont have the tools to swap the props..

To funny I saw this ski on Craigs list for awhile. You got a great deal!

I ran a Solas 13/18 in my 650 powered 550 and it was definitely way under propped. I ended up with a straight 17.5 with ocean pro nozzles. If you have anything done to that 650, definitely prop up. If you have a 28mm carb and stock exhaust on it though, it's very likely that the pump just needs resealed.

I'd be interested in the bare hull, for sure. That was me looking way back when?

 

[superjetguy]

Wow @gpblaster to bad I sold the whole ski to some lucky guy for $650 I needed money bad
