RE: Unofficial
the ESC wont "suck water" it has to be forced through by the action of the motor.
on a regular boat, the water pick up is on the rear of the boat, and water is forced though as the boat moves forward.
on the jet boat, the water inlet is on the rear of the jet unit. as water is expelled from the jet unit, some is diverted through the cooling system.
there are plenty of pictures on this thread of the water pick up on the jet unit.
