Im working on building a 52" Scarab Hull with 3 ProBoat Outboards. I plan to use the middle motor to connect to the servo or servos and tie-rods to the outter motors.
I have 2 traxxas waterproof 2075 servos, with 125oz of torque each.
My question is will one servo work to turn the 3 motors or should i try to use two servos connected to the center motor to turn them?
Also can i trim down the Arms on the motors and connect closer to the center?
Im not sure how much torque these motors will have on the steering system. One of the motors will be counter rotated.
Thanks

I would definitely use two servos. Even with a single inboard motor and a rudder, boats this size need plenty of servo torque to steer adequately. You'll have to see how much prop walk the motors will have, but the small diameter props will help to minimize that issue.
