260hp! Wow! I want one too! I wonder what the range is? I raced stand up jet skis semi profesionally this seems really fun!

ME WANT!!

hehe ever since i saw the ice powered surfboard thing ive wanted to make an electric equiv. Would love to know what kind of motors it uses...

It's supposed to be a new type of pump, one designed for the military. There is a company that makes the pump (trying to get funding). It is a little confusing since they say they have the licensing rights. From what it looks like, the outer housing contains the stator, and the rotor is a donut shaped configuration with blades/vanes extending inwards towards the axis. The actual center is flow through and does not have any blades, which is efficient. They say it can run for three hours, which seems unusually long for something that will go 65mph. Maybe that is peak speed and the cruising is 25-20mph. Still that is exceptional.

Neat but judging from the specs probably could buy a dozen regular jet skis for the price of one of these would run..

looks sleak on paper, but that does not look like it'd be practical or fun in any way at all! the second you go through a wake or wave above about 10cm itll kick water straight into your face. That riding position would be hell on your neck after a few minutes, and I think I could probably jump off and swim faster than that!

edit
just read the article, sadly looks like the author is another person who doesn't understand what hes talking about.
'comes with a 3, 4.5, 5 or 7 kilowhatt hour motor' ????
Im guessing its the size of battery he's referring to. With a ~2hour run time the peak power of this thing must be a mere 4-6kw or so.

Can't believe I watched all of that video, guess I was hoping something better would happen alas it didn't...
Couple of mates had Jet skis in the late 1980 a I could stand about 20 minutes riding them before I was royally bored shit less...I was heavily into racing slalom windsurfers back then, they were a 1000 times more fun to ride than a Jet ski..

yea me too mate. I kept thinking 'yea thats kinda neat, now hes gonna FANG it and that things gonna fly!' or that the shape of the hull was such that you could dive underwater and it would keep you in a tiny little buble of air, so long as you kept your speed up!!

Wtf was that thing in the vid? I thought we were talking about this with the 260 horsies-

ney!



sorry, couldnt resist.

That was the OP, just the post of that weird lay-on-top thing got everyone a little off topic. That jetski still looks bloody amazing. anyone found any more news about em?

Agreed; this thing is anemic! Now if it did one of those cool Jonny Quest type diving tricks and ran underwater, could shoot harpoons at adversaries, and shock the shite out of sharks – then I’d be interested.

Speaking of which, have you ever tried an Aqua-Scooter or a Sea-Doo? When I was a young polywog (yet-to-be certified scuba diver) we had an ICE version that had a 2-foot snorkel which was great for working against the tide to get to a dive spot.

i posted that prone one to keep all the e jetskis in one thread...
(its like a cross between boogieboarding and jetskis, maybe good for catching waves)

looks like that green samba is vaporware..

We will all own electric cars with gas performance and range before electric jetskis are viable... Jetskis are horribly inefficient, and are fuel (energy) guzzlers! Ask me how I know... Plus they are recreational 'toys' which means anything less than gas performance will not be tolerated by 98% of the market. Unless they ban gas powered watercraft like they did to 2-stroke PWC's...

[blake.thomas.80486]

Electric motors have the advantage of no transmission for a vehicle. But that advantage isn't there on a jetski.
They run at constant rpm when full out and the engine is tuned for peek hp at that rpm.

For half decent performance you'll need at-least a 50KW motor. Not practical for the near future.

I had a Yamaha wave runner once and it was fun at first, but quickly got boring. You can only go in tight circles do long before you get bored. Then I took it to the ocean and played with some locals. They were nice, but as we were all shooting through deep water in a bay, trying to get to the ocean over some shallow sandbars, I released the throttle and a guy yelled "don't slow down."

I lost my plane, started to draft, and then went straight over the handle bars, landing in a head and back combination, just like Christopher Reeve. I got lucky and only suffered soft tissue damage and a shattered ego.
