I have not ordert jet - but i entered everything except my credit card-number and the shipping was free (to Austria) - so it seems shipping is free - at least in Europe 
The shipping seems to be free shipped to a European address or collected in Bilbao
Onean / Aquila electric surf board
Av. de la Ribera de Axpe 8, Erandio, Vizcaya
Bilbao, Bizkaia 48950
Spain
160eu from Onean compared to 415⏠plus shipping from Mhz is a game changer.
Impellers 63.6mm for Onean and 64mm for MHZ, Iâve always thought that MHZ was Oneanâs manufacturer.
In October, MHZ is planing to release the complete jet pod for efoils ready to connect to mast and electric box. 
Well, MHZ is a whole jet propulsion, Onean is just a nozzle and the impeller.
You are missing the whole stuff like inlet, shaft to the motor, seals of shaft, bearings of shaft, housing of impeller, bearing of impeller, axial and radial fixation of impellerâŚand I am sure there is still missing some smaller parts.
And then it is still not said, if you can get the (same) pressure/thrust, e.g. if you have too big tolerances/gap of the housing around the impeller you will lose thrust.
but it is at least a start - but for sure i what love to see in the housing of the impeller
and I guess we all in the experiment-phase - and these Onean parts give me in option to have a good impeller ⌠is this 160⏠worth i donât know âŚ
I was just comparing the price of 2 equivalent kits : nozzle stator and impeller spotting that the price of the MHZ bearing was only 255⏠(415 - 160) 
- on the left Onean 160âŹ
- on the right MHZ 415âŹ
What is curious is that this âwhole stuffâ cost half the price of this âHydrofoil kitâ (nozzle+ impeller) in the complete Jet 64 kit costing 649âŹ.
Not obvious the reason why MHZ has proposed this 415⏠âHydrofoil Kitâ to the efoil builders knowing so many essential elements (including the impeller) were missing.
160⏠is a good price so letâs look for some inspiration in the trail opened by the MHZ project :

I found this picture:
thats a view in the caver inlet - on this picture it seems the impeller does not sit âdirectlyâ on the strator
and it is a very custom drive-shaft -
and also found a video where some said the impeller is driven by two motors - Iâm not sure if this is true (double outrunners with one shaft? - but i donân see any water cooling âŚ
any ideas?

Itâs driven by one motor. They have released a board with two jets recently as well. They donât use big motors on their boards, hence the need for 2 if the person weighs more than 85Kg
We just got some of our jet propulsion parts machined to make things more waterproof, easier for assembly and to disassemble, plus more durable and sexy. Really exciting to see!

It is very likely that the impeller for Vefoil will have a higher efficiency than Mhz and Onean. Thatâs why it pays to wait for the VeFoil prototype to be completed.

This would be very nice - but why is this so? and Vefoil nozzel dosenât have strators ⌠(i foud they are important)
I hope that @VeFoil will provide performance charts similar to this one, here after the MHZ Jet 52 Booster - Max. 3,3 kW - 20kg at 13.500rpm⌠23.8kg at 16.800rpm.
@all :it is only a 52mm impeller, as provided on MHZâsite for a bodyboard
As weâre witnessing an increase in performance, I was wondering if this one (two steps down) wouldnât suit our needs. MHZ also have 58mm and 64mm but the charts are not provided ? As a reminder, MHZ have chosen the 64mm impeller (see the two 3D drawings above) as their âHydrofoil kitâ. When we look at Elevateâs figures (0.7KW in flight) the 64mm might be overkillâŚ
@ELEVATE.rocks : as a mouth watering starter, do you think you can show us your expellerâs chart that matches your recent high lift / low drag front wing ? You are the only brand to have chosen the expellers. All the other manufacturers offer propellers ( Lift, CabraTech, Fliteboard, âŚ) or impellers (Eldoridedo, VeFoiil, âŚ)
We used impeller as well (and still use on one prototype) .
We expierienced that no matter what optimization we did (Diameter nozzle length for pressure increase a.s.o) that 2kW was the magic number for cruising with the e-foil (Our optimum at the end was about 60mm diameter with 40mm nozzle and about 9500RPM)âŚThats why we decided to change to more efficient propellers. So if anyone finds a solution to ride with less than 2kw, congrats !

Can you tell what are you using know? Prop + Motor + Gearbox Reatio
Are you saying less than 2Kw with a jet?
Yes, we have stators (diffuser) you cant use a jet/impeller without them, they are critical 
We are still 3D printing various stators as they change performance and we are working towards the best possible setup. We tested the MHZ nozzle and stator and found our own nozzle design generated 9.4% more thrust, and we believe we can improve on that with our newer nozzle, stator, and impeller designs we are working on. Exciting times!
@SoEFoil Yes we will provide detailed chart just like you want once we nail down jet specs, no problem. I agree 64mm is large for an impeller, but if you lower the pitch it can work as direct drive.

Indeed. What is amazing is that jetsurf research on impellers/stator coupling is more than 50 years old and you are still making significant progress by trial and error (or by the mean of another skilled backer 
) .
By the way, which impeller diameter did allow you to gain 9.4% wrt the MHZ 64mm ?
Yes VeFoil, this is a very correct view (pitch adjustment).
Just for fun, I took @pacificmeister 's original cad to build this jetdrive with 64mm impeller which is a bolt on for a direct drive setup. The jetdrive has 2 pieces which thread into each other once the impeller is secured.
I need to tweak the impeller some more to get the thrust I need to plane.
I have not tested it yetâŚstay tuned.

Let us know how it goes! Would you feel like sharing your impeller cad model? Iâm finding it really hard to design one
