How does a steering wheel on a boat steer the boat?

Answer:
The steering wheel on an outboard powered vessel, turns the engine port and starboard, (left and right) to steer the craft. On an inboard/outboard powered vessel, the outdrive unit is steered in the desired direction of travel. For an straight inboard powered vessel, the helm is connected to a rudder which when turned, steers the craft port or starboard.
