New Inverse Hull

[schicks]

Just ran the poorman set back pump. Im totally pumped, more thrust, turns on a dime, nose pops up better, doesnt cavitate or porpose. Looove it, couldnt be happier.

I just noticed the arrow…. That’s pretty cool…

I like the poor man set back too, more water to process

So it that a 3 inch Pump Setback then?

 

[schicks]

Yea; whatever the thickness of an extra wear ring is.

Any more photos of your Pump Setback Project?

Did you add more Inserts for the extended Pump? Used standard Jetski Brass Inserts? Rivet-Nuts? How many Bolts are holding the Pump in place? 4 or 6?

Did you swap Impeller Shafts? or somehow add a 3" extension?

And the Steering Cable? Added a Coupler Nut?

I'm going to be doing the same 3 inch Pump Setback on my Square Nose using an additional Pump Section, Riv-Nuts and swapping in a longer Driveshaft. Will have the Pump rebuilt during the Shaft exchange.

I used oem brass inserts. There are 8 inserts, but 6 bolts. 4 in wear rings, 2 in nozzle. custom shaft from squatchcrap, steering cable extentions from mcmaster. I was worried id have to reprop, but its goood. This ski has a setback motor with gp800 midshaft as well.

Does that work pretty good? Bought a PJX hull a couple years ago that had that same pump setup but never got a chance to ride and build that ski before I had to fire sale it to help pay taxes.

Working with some prepreg at work on a huge government project; gaining knowledge. Hope to do a prepreg hull this winter. Im gunna shoot for 45 lbs total, full carbon and see how it holds up.

I can tell you from xft/pjx builder, that the 2 wear ring setup doesn't work right . Funnel intake into the prop, not tunnel.

Can you pm me? Would like to pick your brain about a pjx

Carbon prepreg tends to be a little dry and stiff for jetski use. Plus its expensive. If you can get free material then go for it.

Another Michigan hull builder is here and with a little support, i will be here to stay. A little background; ive been obsessed with jet skis for 23+ years, I bought my first jet ski when i was 14 years old. I've built several one-off full custom jet skis and became really good at working with composites and thoroughly enjoy the challenge and reward of the end product. I am very particular on how stuff gets done, no detail is over-looked and i think my work speaks for itself. Here are a few examples:

After building several full custom skis, the next step was to make my own molds. I really really wanted a textreme hull, but didnt want to buy one. So i figured ill just build one, easy enough. Well, after 2 years this is where i am at... I built my textreme hull and it turned out so dang good, i made a few more hulls to share with others.

Inverse Hull details:
Started with a superjet.
* -1.3" off rear
* nose rocker closely matches the slope of a rickter evo
* enlarged pump intake track
* widened and flared rails
* Hood seal system inverted and raised
* 16 inch wide tray, front to back
* Full front foot hold
* Several other mods that I will keep secret for now.
* setup for couch mounts
* Oem 144 pump shoe installed
* 2 3/8" water lines, 1 1/2" trim tube
* 2 oem tray drains
* pump inserts are oem yamaha inserts.
* all other threaded inserts and waterlines are stainless.
* I don't turf skis, foothold turf is very individualistic, but i will turf a ski for buyer if requested.
* All hulls will come with a Michigan Title!!!

Layup
- all parts are built using resin infusion, because its the best! and the right way to build a ski, even the ride plate and foot holds are infused!
- fiberglass layup with perfect visual carbon.
- hulls weigh 83 pounds and are very strong.

Every ski i build is built like it was going to be my own and i am very proud of the craftsmanship i put into each one (just look at my hood to hull seam fit, then look at any other aftermarket hull). Pictures don't do them justice and are a must see & ride to appreciate. These hulls are what the superjet should have been; and are perfect for surf, boat chasing, recreational riding, and does WOT smoothly with no weird chine walk or twitchiness.

As of right now, I have 3 hulls for sale (2-black 2x2 carbon, 1- purple mirage 2x2 carbon top deck on black carbon bottom). As soon as i sell 2, i will buy more material and build more. I do not plan on taking orders, all hulls will be built then sold at a first come, first serve basis for now.
