Custom/Hybrid Melmack's very unique 300sx build

May have stumbled upon an investor that would not only help with the initial startup and protptype but has vast experience in organising and promoting busneses. Will be speaking with them more in depth soon.
 
Interesting thread, whats the latest?

Btw i weighed my 550cc/ 44sbn/jet power manifold/ factory half pipe and my 750cc/40 Keihin/ PJS 650 ex 2650 pipe when i first did my 550/750 conversion. There was a 9 lb weight difference, 76lbs for the 550 and 85 for the 750. A lot of that is due to the lighter weight pipe on the 750. A full pipe on the 550 would cut a decent chunk of weight. Not disputing anything youve said just adding info I have collected. A friend has an old 440 superstock with a full pipe and that ski definitely has a lighter nose feel than my 550/750. I havent been on a 300sx but really would like to try one now!

Really cool engine selection. I havent seen that type before.

Also very innovative idea about the fx1 pump! If i could find one for cheap i have been thinking of putting it in my 650 wave jammer. I am worried i might be at the 500 pumps limit when i port my 650 or put a 701 in it.

I have a much lighter pipe on the 550. its a kerker.

U too Smoof. Weve had some good times! I've reached back out to Moller the Rotron guys. We'll see. Still looking for a used axiro 50 kart engine if anyone locates one
.

Welcome back! Any new updates in the 5+ years?!
Thanks. Sry for the slow response. kids and life took over all my priorities. Slowly tiptoeing back into things.

RHASS built me a new/better through hull bearing system. It is hybrid to allow a Yamaha mid shaft. Need to measure for a new drive shaft and then ill be dropping a properly tuned 300 until I get a Group-k built 550reed motor(Hoping to have deposit by end of summer, have all the parts). Still looking for an axiro50 kart engine but no luck. Moller skycar engine is a dead end but I am not giving up as there are sources for the rotary engine in aviation now and not ruling out the idea of finding a 50ish HP 4stroke.

Meanwhile, I'm looking to pickup a sick Wamiltons old school flatwater ski(Octane style) and ride that for fun here in New Braunfels and with the crew that rides Lake Austin.

Currently have a 550sx with a 650 swap that I am tuning, cleaning up and selling soon as I get my Wammer on the water.

If your reading this again, thank you!

I truly appreciate looking back at this thread to remember all that went into this. So much support and advice from everyone. I took quite a few years off on this but I have not lost hope that I will, at the very least, get my hands on an Wolfe/Axiro engine and prove the prototype works with the rotary. I still proudly display my 300 "Project Tiger" in my new shop, just waiting for me to find the time to do a little here, a little there to figure this all out.

I have been focusing on raising kids and far more important family things than dreams. We have all seen a wave of new innovation in the stand-up world and it is exciting to see Yamaha back in the game, sorta.

My kids are reaching the age I was when I got into the best sport on earth and I want to pass down this love to them. I almost bought a new SJ but I just couldn't buy something so easy. It's a good ski but as much as they tried, Yamaha didn't hit the mark with pure free riders IMO. We need a smaller, lighter OEM option like the Footrocket, but mass produced, maybe SMC or plastic like See doo has done, I wonder why nobody has tried something else that I think is being oddly overlooked. There is a very light, very strong material that is cheap and fast to fabricate. Never seen it used on a ski. Maybe that will Come into play.

Wherever this heads: Lord willing, if I am able to fund the startup company by some miracle to mass produce these, I will remember all the help, advice and amazing support received here.

Something to look forward to is that I have gotten quite a bit more media savvy. Don't expect me to post here frequently but I intend to add more media to give better at illustrating the project.

Till the next update, here are some things I never quite covered. Some facts I never shared and a couple observations:

*First, I don't think the X had emojis back in the day. :eek: Or at least I didn't use them then. Also, when I say "The X", I am not talking about twitter o_O

*I did have to sign an NDA with two separate companies if I remember(1 for certain). Mostly, I just couldn't share design details other than company name, HP CCs and all. Both of the companies were mentioned by other Xmembers in this thread. Cannot remember my NDA so Ill leave it there. ;)

*The "Project Tiger" name is a reference to two things: First, there was a BOB hull mentioned once in the last 12 pages. Find that guy and maybe he has a picture of that BOB hull still. You will understand. Very cool paintjob. May have been from Cincinnati or something.

The other inspiration for the name, was hinted at over the years but never explained. People like Preston Tucker and Howard Hues inspired me to invent and innovate my whole life. In the "Tucker" film, Preston repeatedly sings this old song "Hold That Tiger" that apparently was popular back when he built those 50 cars, against all odds. Tucker, the movie version anyway, inspired tenacity. That is something I know this will take to ever
see through.

So, the BOB hull, with Bangle like paint scheme and the idea of building this thing, no matter what it takes, with innovation and tenacity Is where "Project Tiger" came from.

*I have all kinds of ideas in my head. Some that would probably cause interesting people to show up and ask questions :cool: so, I just keep those ideas safe in my head.

But while I haven't made nor may ever make my own free energy device ;) I still intend to see this "Project Tiger" through. Thank you for staying tuned!

See if you can get your hands on one of these :

In the meantime that 550 reed should run really well in there , I ran one in mine for years but it was held back by the 440 pump , I would be interested to see how that 550 setup would have run with the 650 pump installed.

Good to hear from you @WFO Speedracer !!! I was going through the post early this morning and re-reading all your jetting and other input. So very much appreciated!

I'll look into that one motor when I can. Certainly a close fit for a direct swap into a SJ, like the Wasserjet Idea.

For the record, I never saw any of that drama that was removed by admins. If it was about the Wasserjet, I can only imagine how that went. I am disappointed that apparently did not work out and I would love to know what was their biggest set back.

So here is where the project sits as far as the rotary goes:

Rencraft is a dead end(not one response in 10+ years from them) Rotron rotary is discontinued. Moller does not share the vision. The UAV guys are getting printed funny money for these things. I don't have a US backed money printer, nor time to cloud fund a 40k aircraft engine just to put another 40k into r&d to make it mass producible.

All this project needs is that Axiro50 engine, or something similar. Once that prototype is built, the bugs worked out and riders, dealers, manufactures, can see my dream in reality, on the water in a fun, small, playful and affordable platform, that could sell to the masses and be fully 50 state legal, I believe this will finally happen. When this happens, I believe we will see a stand up renaissance like we could never have imagined.

Anyway, I reached out to a UK company last night and they got back to me this morning. I have sent a reply and who knows.

I ask for a few things from those interested in this that want to support this, for now:

  1. Prayers that I will balance my work on this dream with my wife, my family, my faith and that those things take priority over this. Prayers please that I will remember "If God wants this to happen, so be it. He will give me what is needed to see this through."
  2. Please, help me find a running Axiro50 Kart engine, new or used, to prototype in this ski. If you have a good lead or something, please email me at melmackman@gmail.com with the subject "Project Tiger" so it stands out.
  3. Please share this thread so some fresh eyes might find interest in this too.

Thank you!
