2022 Yamaha 25HP Four Stroke 20″ Outboard Motor
A 25HP four-stroke outboard motor F25SWTHC is a propulsion system typically used on small boats. It features a 20-inch shaft length, which refers to the distance between the transom mount and the propeller hub.
The motor comes with a tiller handle, allowing the operator to control direction and speed. It can be started using both an electric start, powered by a battery, or a manual pull-start method.
One notable feature of this outboard motor is its power trim and tilt system. This allows the operator to adjust the angle or depth of the motor in the water, providing better performance and fuel efficiency. The power trim and tilt can be controlled either electronically or manually using a hydraulic or mechanical system.
