hello every one, after 3 month of no use … just plug it again and its work perfectly.
for information i met cops on boat.
They were really interested by this concept. they take a lot of pictures.
they said : " we dont dont what is law for this kind of board so we will not ask you anything "
hope it will stay like that a long time.

In many European countries, you don’t need a licence below 6HP or 4500W.
Did they ask you your electrical power ? Did you give them your address 
?
In Croatia, u can use 1.5HP and under 299 cm length. Anything over = licence and registration. However, we are so screwed we got different laws depending on the region of the country. 
Gobbla, we are building a similar very short / very thick board.
How wide is yours, and how do you start when the engine is still off ? Are you able to climb on it from being fully in the water ? Or do you start from a platform or pulled by a motor boat ?
Thank you
philgib, my board is 1800 x 610 x 140 mm
almost 110L
i start on my knees, i can sit on it :
it’ s really convenient when water is cold or if you want to take rest out of water.
only problem is when there is waves , it take more time to get enough speed.

soefoil , they did not ask me any thing on power. Same in france 6HP. but i have boat license. i m more affraid about insurance.
@Gobbla, IMHO, not sure at all but seems to make sense, the 4500W limit makes it all good or all wrong:
- If you say 6000W to the police you are fined and not covered by your insurance in case of accident because you are ignoring the law.
- If you say 4400W to the police you are OK and covered in case of accident with the civil liability contained in your home insurance because you didn’t need a licence.
About your board:
1-110l and it floats : did the following relationship work OK for you ?
Board volume (L) = rider weight (kg) + equipment weight (kg) + 30
2- I am intrigued by your bevel on the rear of your board like on 2019 commercial foil boards. Did you notice any positive effect on take off or touch downs ? You have modified this principle by adding a plastic sheet + big black shims. Any reason ?

@Gobbla Where did you buy your waterproof connectors? Could you put a link up? Thank you!

this is my load list :
pilote + suit : 75Kg
board mistral re cut : 14.4Kg
motor + reducer + pipe + fixation : 4.3kg
case + ESC : 4.8kg
batteries : 4kg
foil gong : 5.2kg
fixation of foil : 1kg
total : 109kg
no 30kg margin but seems working, weight are measured with scale
mybe board volume is more ?
for point 2, this bevel was a mistake , i was expecting some short take off.
But result is opposite. Due to short lenght of board nose of board was getting up . it was difficult to take speed. i add this plastic sheet to compensate this bad cut. now it’s working fine

i did not buy it. it is standard connector in 3D printed housing :
this is my actual one :
inside there is XT150 connector.
in my next build i will use this one :
i m now using XT90 connector. i m printing it with multiple color do not not mix wire.

Awesome! You got really Nice engineering skills. Would you mind sharing 3D files for the new connector? Thank you so much for your reply.
This is 3d model :
on XT90 you should print it without support , one ring is already in model to make better gasket groove. after printing you can easyly remove it with small screw driver.
hope it will be usefull for you

Thank you very much @Gobbla! Regarding the XT90, and suppose that you are using AWG10 cables. Is that enough for our power hungry efoils? A friend of mine, who is electrical engineer says that I should minimum use AWG 8 cables, because of the lenght of the cables, and therefore XT150 connectors.
What is your experience with this?
hi , i m actually using 8mm² cable similar to AWG8,
no problem with it , stay cold.
i will use 6mm² cable similar to AWG9 ?
i m betwenn 20 to 30A during flying, 40 A during take off, shortly.

hello, update of the day : GPS speedometer :
standard GPS speedometer :
https://fr.aliexpress.com/item/Aliexpress-Cheapest-GPS-Speedometer-Hud-Display-Car-KM-h-MPH-C60-Car-Electronics-Better-Than-A100/32915019051.html?spm=a2g0w.10010108.1000016.1.2103638bbgWDd3&isOrigTitle=true
accuracy seems ok :
now just need water proof housing :
here is 3D files :
water proof test done succesfully, real test in condition not done yet.

Nice simple waterproof case! Are you using a oring to seal?
Also what have you used for the clear display window and how have you waterproofed it in place?
@g.gregory8 yes oring seal is possible, in my case i use silicone bed ( cheap )
for clear display it is polycarbonate sheet stick with same silicone (bathroom silicone)
