Here's why:
* Outboard motors are typically smaller engines designed to be mounted on the transom of a boat.
* Tillers are the long, horizontal lever connected to the engine's steering mechanism.
* The tiller allows the operator to steer the boat by moving it left and right, which in turn rotates the propeller and changes the boat's direction.
Larger boats with inboard engines typically use a steering wheel connected to a rudder system for steering.
