Hey all !

I am shopping for Brushless set up for my boat. this is what i have come up with .

the jet drive unit im installing has a max RPM 20000
So, 2700KV @ 7.4v = 19980 RPM
I will run 2 1500mAh 7.4v 25c 4s in parallell
So, if discharge A=(mAh)/1000 x (c)
3000/1000 = 3x25 =75A
do i need a 75A or higher rated ESC ?
i am looking at a 35A ESC With a 5v 1.5A BEC
Will this work with a 2.4 ghz receiver and digital servo? or do i need a BEC with 6V 1.5A.

Here are the items:
