Hello all!
I am new in this forum and I am building dual motor efoil/jetski hybrid and i want built it with high quality components. I will appreciate your personal advice for following pionts:
It seems that you want a very porerful system. Go high voltage because you need lower amperage. However finding a high voltage esc is pretty difficult. Maybe go into ebike escs and cool them somehow with a Waterblock or so. For the motor I really don’t know. Perhaps mhz watercraft. They have a motor for this kinda application
Br
dual as 2 motors, or two application efoil and jetski , or one motor for a flying jetski ?
for jetski will you need x5-8 at least the power than for a efoil board, and a big motor would be to heavy for the just a efoil application
so you need to give more informations
Please be safe with your voltage in water Electrocution is a real danger. 72v = crazy !
what max voltage use for efoil?
I mean dual moror (2 x motors)
it will not be efoil and it will not be jetski, it will be like watter scooter, small and light jetski with efoil motors … 3D design will be ready next weeks and i will post here pictures. Difficult explain without 3D 
In short - what is the most poferfull battery, controller and motor for efoil? it will be good for start and for tests
Outrunner 80100
Trampa vesc 75/300
Battery : home made Molicell or lipo tattoo
I would say
I use two Surpass hobby 56102 600KV motors with 6S6P in my jet board
Not perfect, but it does work.
Building version 2 now. Same motors (for now) but powered by 12S12P
I’d go watercooled QS motor 138 70h with votol 72150 controller. It can push 20kW together with a lipo battery pack. Weight is a bit high but not so critical for you and i never heard anyone burn this motor. i’ve driven one for 30 000 km without issues.
