Hi chris, yep it was CNC'd out with the router, sure beats doing it all by hand. Hull is 620mm long, have also started plans for the marathon river race jet boat hull, maybe have it routed out early in the new year.
So you found me then?
Take care and hope your well.

hull2.jpghull3.jpgHi guy's, just a quick update,
Molds are done, well I had to resize the hatch plug so it fits better, but I have the first out of the mold and have started to fit it out , hoping to give it a run Friday the 20th, should be releasing them after the run.
Cheers all Mickhul6.jpghull.jpg

I guess the router is working well MickieB ....

Hull looks pretty good buddy, look forward to seeing the difference between this one and the smaller one, when you get it runnning.

Cheers
Chris

Hi Mike, as requested

I will have a instruction sheet for the installation of my drives into any hull available in the coming days.
Thanks for the kind words on the new hull, I had to go back and re CNC out the cowl plug as the sizing was all wrong, so hoping to have the molds for it done this week. It should be a perfect size for this jet unit, and still be quite lively ...
I will update more pictures tonight, Regards Mick

Looking sweet!
What's the roll cage made out of?

[mickieb49]

Hi Jeff, the rollcage, is made from 10mm alloy tube with CNC'd clamps, these will be included in the hulls. Just need to get one to you so we can work out the sticker kits.
I will upload the video of the hull after Wednesday, providing all goes well I will release the hull/jet unit kits this weekend.
Regards mick

Looking forward to it!
Btw we need to make some guage cluster decals to go with the kits.
Thought it would make a great addition!
We should also figure out a logo for you.

[mickieb49]

Hello All, just ran the little jet, pretty happy with it , will upload some video when i get home
Still have to play around with the COG and Trim but overall it performs very well and isn't as twitchy as the shorter version.
Jeff the idea on the guage cluster decals would be great, i will try to get the hull and unit over to you as soon as possible, i will also send you some pictures of the real Jetsprint Boats that race here in Australia, so it gives you something to follow off.
Please stay tuned as video will be comming up.
Regards Mick

Ok guys , here is the video.

So now officially the hulls are ready, It will take a week or two before I will have a few hulls made , but I am now taking orders.
Hull , Jet unit, roll cage, dummy drivers $300 USD for the kit plus postage.
Hull on it's own is $175 USD.
The Kmb/Kehrer hull/ jet unit that I tested the jet unit is also up for sale, you will need your own electrics, asking $250 USD plus shipping.
Take care and best wishes for Christmas
Regards Mick

Nice boat is looking good for first time out!
How do you think it would do with a smaller motor like a 36mm?
Do you think the 40mm motor is necessary?
What is the optimal rpm for the unit as you have it now?

Hi Jeff, mate I think it might go OK, just it may draw a few more amps as a 36mm motor is typically not as powerful. But if your keen you may be able to test it yourself when you get yours.
As for the rpm, I have not tested it over 30000rpm, the efficiency drops off around the 28000 mark.
I am now looking forward to seeing what sticker kits you can come up with.
Regards mick

[monojeff]

Certainly will do some testing.
I bet it would run well with PSpec power.
It seams you have more then enough with the 4074 motor so I don't see any reason using a smaller motor wouldn't be ok. I wouldn't think amp draw would be much higher maybe someone else could chime in on that.
