aka the "Polaraha Octajet" :biggrin:
Better late than never… I have had this ski built for a little over a month now, but have not had time to post anything. A handful of people know about it and a select few have had a test ride as well… :brap:
Oh, and I did this as a “My Ski” thread instead of a “build” thread because there is really nothing special about how it was assembled (and I didn’t have assembly pics). If you have seen a SJ being built, this was just the same.
So here goes:
I acquired this hull from Pat Bogart at x-metal back in the spring (details here). I had been building a OEM SJ hull that was to be as lightweight as possible: (build here, for sale here), but I was just too busy this year to ever see getting it finished any time soon. So I saw this hull from Pat and since I already own an OEM Octane, I was very intrigued. I went ahead and bit the bullet, bought the hull and began to put it together (slowly…). I always knew the Octane hull had great potential, but was still a little doubtful. This particular hull is hand-laid, semi-lightweight fiberglass with carbon reinforcement. It was originally built by Wamiltons for an overseas customer. It is definitely light for an Octane, the Hull, hood, turf, and front exhaust w/ hose weighed 120 lbs. The other cool thing about this hull is that Wammer built it to accept a “small block” Yamaha engine (62t based). Since I had all my parts lying around to build the SJ hull, it would all drop right in.
Big thanks to everybody that helped get this hull cross-country for me… Pat, Mike Mosquini, Jimmy Jawbreaker, Toby & Scum (Steve)
Here are the Specs:
HULL
I have mentioned this before in some other threads (such as superramjet’s Octane Build)… This thing handles like NO OTHER OCTANE I HAVE EVER RIDDEN. It is amazing what a lot of weight reduction, coupled with a lightning quick responsive engine will do to the handling of an Octane. It handles like a dream… very SJ-like, yet way more stable. And just super comfortable to me. It feels so light and just hops out of the water! I couldn’t be happier!!!
I have concluded and I’m sure Tom will agree that bigger hulls (octanes/SXRs) are greatly underestimated and dare I say…. the future of this sport (hint, EME, Trinity... anyone???). I was always hardcore 100% SJ, with an appreciation for the Octane, but now I think its the other way around!
I will try to keep this thread updated as I make changes and upgrades…

forgot to mention... The complete ski weighs 299.5 lbs. with battery, no fuel. Complete, ready to ride! :bigok:

Here are the Specs:
HULL
- Semi-Light weight Wamiltons Octane hull, built for Yam 62t drivetrain
- Dual Wamiltons Scuppers
- Wamiltons Freestyle Octane Hood
- X-Metal bracket, -2 pole, turnplate, bars, hood hooks (had to cut them down to fit the Octane)
- Watercraft Factory carbon chinpad, cut way down, reshaped and covered in embossed hammered vinyl.
- Gas filler covered with Carbon fiber plate.
- Turf was already done by Wamiltons but I pulled up the back to add a kick-tail and additional padding.
- Wamiltons SJ carbon ride plate, that I cut & trimmed to fit the Octane hull w/ D-cut
- Trimmed off back flange
- Removed the Wamiltons sponsons (tubbies) because I did not want the weight nor did I believe this light of a Octane hull would benefit from them (I was right BTW)
- I plan on trimming another ¼” off the bond flange over the winter. This will save a little more weight and improve handling even more IMO.
- +8mm stroke x 81mm bore Lamey PV built by Team Scream. – (I bought this engine 2 years ago in a Pro-Mod race Blaster) IT RIPS!!!!!
- MSD Digital T/L – currently not mounted or wires routed the way I would like, but I was in a hurry to get her running! Will re-do this winter.
- Full Spectrum dual 46 carbs w/ Boyesen/Full Spec Manifold
- TNT chamber with ceramic coating
- X-Metal Waterbox
- OEM Yam 144mm w/ TBM pump cone – (shortest cone used)
- Skat-Trak 144 12/17 Mag pump impeller
- Worx intake grate
- Pro-Tec trim Nozzle, flipped to up position. Does not have much travel now, but I plan on making some mods to the nozzle over the winter to allow more throw.
- Nozzle bored to 84.5mm
