Super Jet Shortened Superjet with set back pump and Dasa power

[ou812]

After many months of building my Superjet it is finally getting close to hitting the water. I started with my 97 hull. From there I stripped the hull down and took out all the water logged foam. I shortened the hull 4” by cutting a section out of the back of the hull and moving the back section forward to retain the existing ride plate inserts. By cutting out 4” I was able to still use any ride plate that will work on a SN. I added a layer of 1708 biax for reinforcement to the complete hull and glassed back in the rear pieces of the hull.

I then used a wear ring and Blaster drive shaft to set the pump back in the hull 3”. While the tray was cut open I glassed in a third set of pump inserts for the now set back pump. Now I had to extend the steering cable thru hull attachment. For this I threaded a piece of ½” plumbing and used a plastic nut from a bathroom faucet to tighten the extended pipe to the hull. I added a coupler and at the end of the extended pipe and re used the existing steering cable fitting. Now the cable sets back 3” to match the pump. I removed my existing Blowsion one way valve for a Epic scupper valve. I also picked up a new Epic light weight coupler. These two parts look great and the magnets on the scupper valve work great to keep it shut.

For the engine I was going to go with a Dasa 850SS from Nuklear6 but when he came out with his 4mm stroker version of the stock stroke cylinder I changed my mind and went with that. Chuck was great to work with during the engine build and couldn’t believe how nice these engines were when I received it. I picked up a set of 46 Blackjack’s with Mikuni intake and reed spacer from Hardcore.

Now with the added power I went with the new Solas SS mag pump I got from Cold Fusion. Then got a Hooker 11/17 impeller and bearing/seal kit from Jetmaniac.

Freestyle 650, Nuklear6, Jetmaniac, Hardcore, and Cold Fusion all have been great to work with on my build.

This is just a ride plate I have. I will start with a stock D cut and start shortening it from there.

i'm going to try my hand at some composite ride plats. I'm also doing -3 hull. planning to testing an OEM length plate, d-cut plate, and a -3 plate to see which works. if my project works out, look for plates in the marketplace. or if you're interested pm me.

Got it yesterday!!! but i can't start until the weekend. due to lay up times etc. should have some solid molds next week.

This looks awesome! How far did you shorten the rear of the hull? 4 inches? 6 inches?

P.S. I shortened my hull similarly, but left all of the ridges where the ride-plate rests on at stock length (whereas, you cut them shorter).
I was worried that the torque from the rider weight could cause the forward ride-plate insert-mounts to rip out of the hull...
Should I not be worried about the insert-mounts ripping out?

((The foam needs to be sanded off from vacuum bagging, but you see what I am talking about))

@ JGringo
How much did you shorten your hull?
I pulled 3 off the rear and rockered the nose which shortened an addition 2-3 in.

I cut mine back 4". I still have 4 ride plate mounts so I'm not worried about them ripping out. As long as you have 4 you should be fine.

Sweet build, looks like your going a great job at it.

I shortened my sides around 6 inches. I am past the center mounts... I would probably would rip them out :-/

I have an extended ride plate to promote the ski to plane out, but shortened the sides to give a rocker, banana feel.
I still have yet to test it though, so it's really a crapshoot at this point.

[garretonufer]

i know the feeling, i pulled the nose up and took 3 out of the rear. really have no idea how it will ride.

 

[O2VW1.8T]

Im at -3 and love how it rides. Need some tubbies and i'll be set.

 

[garretonufer]

yeah tubbies.. been thinking about a set of them. bye bye money.

Got the tray foamed using EPP foam and then a top coat of expanding foam to hold everything together and give a base for laying the fiberglass. Widened the rear of the tray and modified a set of foot holds.

looks good any new pics

Its all complete now. I have ran 4 tanks through it and I am starting to get it all dialed in. I'll post pictures soon.
