Hola Carlos, I'm guessing that you're interested in the current under load of the servo. Manufacturers don't usually give this in their technical specs. But I have a boat of similar size to your ETNZ with a servo of similar power and the 5xNiMH power pack seems to provide enough amps for the servo.

Servo 3801

Use a 3802
PS A little less torque at 6 volts but more speed

current usage is very low. You can get a days sailing out of a set of batteries. It is not like using a motor running a prop.
