Freestylegeek's squarenose conversion

[sjetrider]

Watercraft Factory (Steve) had a version of the shortened hull at Lanear build off. Only issue he had was the scupper wich it seems you have addressed.
He won the buikd off also (rightfully so)

Does the back of the topdeck extend beyond the lip/bottom hull then? I have some trouble picturing this.

The top deck will fit the same as the stocker.
Once they are joined together, I will cut off the 'vertical' section of the lip.
Take a look at the back of Malone's boats, and I think you'll get the idea of what I'll be doing.

 

[freestylegeek]

Looks good geek! so cutting the hull isnt really supposed to hurt other tricks? I was still debating that since I'm not that dedicated to only tricks.

hmm, i should get motivated and try to keep pace with you guys...

Sergio mentioned that the shorter hull uses more throttle to adjust the attitude of the ski, rather than body position.
That's one of the reasons I only cut 2" off the back.
Sergio has gone as far as 5", but he prefers 4".
He recomended 2" for my height and weight.

 

[freestylegeek]

So is the bottom deck of the RN and SN hulls 100% identical?

RN pump and everything fit a SN like original?

They are the same.
The nose is different, and the roundnose hulls had screw boss' where the bulkhead is held in place during assembly.
Other than that, everything will bolt right in.

Does anyone know exactly how long Malones hulls are???

Has anyone ever tried taking 2"s off the back of a SJ? I cant wait to here how it works.

I was told Malone's hull is 3" shorter than an SXR.

 

[freestylegeek]

That shorter hull will make a huge difference!!:biggthumpup:

Cool build Matt, keep us posted:woot:

This boat should be alot lighter than an oem roundnose .That SMC sure is some dense heavy stuff:frown: Unfortunetly, most of the weight lies in bottom hull itself.

Do you have a front nose mold to rebuild the lip area?

Thanks Steve!
Even though there will still be a lot of weight in the bottom hull, I am hoping the ski may feel a little more stable due to the lower center of gravity.

Sergio includes a front lip that I will glass in.
That will be a HUGE help!

Now, I wonder what kind of footholds I should put in this thing...:dunno:

 

[freestylegeek]

The square hull has six inserts for the rideplate - roundie (at least mine) have only four.

Which actually comes in handy when you're shortening the hull.
Even 2" will eliminate the back two inserts.
With a Squarenose bottom, I can cut a stock rideplate to fit, then bolt it in place with 4 bolts.

 

[freestylegeek]

... only component that is different is that the intermediate hsg on the 90-93 has a different bolt pattern.

One of the big reasons I chose a 94 hull to do this on.
It's the same bearing housing as the 96-07.

nice.

OMG you’re really modifying this hull!

Do you think your steering nozzle will hit the sides of the hull after its two inches shorter.

Just curious where do they glue the hull halves together, is it glued between the top and bottom, around the rails or both? What type of glue are they using and how hard is it to separate them?

Cool project....be careful, I hear there is a huge shortage of metal flake:cool2:

I should chop off the back of my SXR... wonder what that would do???

The steering nozzle will have even more clearance with the hull being shorter.

The halves are glued primaraly on the top of the bond flange.
Some of the adhesive may work it's way down the vertical edge of the flange, but it's designed to be bonded on the top.

I will be using Either MarineTex or ITW Plexus for bonding adhesive.

On a side note, one of the nice things about buying a complete hull from XFT is the fact that he has equipment to bond the top and bottom with epoxy resin. Basically, it creates a 'monocoque' type design where the material is all one thing from top to bottom - no bond line.
It makes the structure lighter and stronger.

It's a good thing I saved half of my metalflake from last time then! LOL!:cool2:

I will be modifying my squarenose hull over the winter and was planning on shortening the rear also. What are you doing about the exhaust tube? Getting rid of it, or just shortening it also or letting the additional 2inches stick out inside the hull?

Plexus rocks! Although it is rather expensive and not easy to get from any retail sources. I have used the MA310 on smc before and it is incredible. Did my last set of footholds with it too. So easy to use, no measuring or mixing, minimal surface prep required. I have been hoarding some tubes of the 310 for my build!

I am eliminating it, and doing an XFT rear side exhaust.
I'm real currious about what tailstands will be like with it.

OK then, sounds like you've run into the same problem I have!!:banghead: :banghead:

Where the heck can you get it from?
Also, how many tubes do you think you'll need for the project?
If you can get any more, let me know and I'll buy it off you.

This is going to be an awesome thread.:arms: :Banane01: I am doing a square conversion soon as well. I hope to get the topdeck off in a few weeks and get started.


Keep it coming Geek, I'm sure the thing will be awesome, I can't wait to see it in all it's metalflaky glory!!!:hail: :woot:
