What is contained within a portable outboard motor?

A portable outboard motor typically includes an engine, gear case, and propeller as its main components. The engine provides the power necessary to propel the boat, while the gear case houses the mechanical components that transfer the power from the engine to the propeller. The propeller is the part that actually moves the boat through the water. Understanding this composition is essential for recognizing how outboard motors function and the role each component plays in boating.

The other options reference components that are not found in a portable outboard motor. For instance, a steering wheel and rudder are associated with boat control systems rather than outboard motors specifically. Similarly, a fuel tank and battery may be part of a larger boating system but do not define the motor itself, which focuses on propulsion. Lastly, a drive unit and sails pertain to different types of boat propulsion and navigation systems, further distinguishing them from the components of an outboard motor.
