MFS3.5CS
Marine Specialist Insight: The Tohatsu MFS3.5CS (MPN MFS3.5CS) is the definitive upgrade for boaters who need a bit more "punch" than a 2.5 HP without any additional weight. As part of the newly designed "C" series, this 15-inch short shaft motor features a larger cowl for easier maintenance access and 360-degree full pivot steering. It is the gold standard for small inflatable tenders, rigid hardshell dinghies, and square-stern canoes where simplicity and reliability are the top priorities.
Reliable 4-Stroke Power in an Ultra-Portable Frame
The Tohatsu MFS3.5CS (MPN: MFS3.5CS) is engineered to deliver dependable performance in the most compact package possible. This 4-stroke engine utilizes an **integral fuel tank** mounted directly under the cowl, eliminating the clutter of external tanks and hoses. The 3.5 HP output provides that critical extra thrust needed to move against tides or wind, making it a safer and more versatile choice for coastal explorers.
Operation is exceptionally user-friendly thanks to the twist-grip throttle on the tiller handle and the front-mounted shift lever for Forward and Neutral gears. With Tohatsu's unique 4-point vibration dampening system, this motor runs significantly smoother than traditional single-cylinder outboards. Its 360-degree steering capability allows for effortless reverse maneuvers—simply rotate the motor 180 degrees to head in the opposite direction.
