MFS9.8CL
Marine Engineer Insight: The Tohatsu MFS9.8CL (MPN MFS9.8CL) is a legendary powerhouse that holds the global title for the lightest 9.8hp 4-stroke in its category. This 20" Long Shaft model is the definitive choice for sailboats, high-transom skiffs, and as an auxiliary "kicker" motor. Unlike single-cylinder engines in this class, the MFS9.8 utilizes a twin-cylinder SOHC architecture, providing smooth, vibration-free performance and superior low-end torque for moving heavier displacement hulls.
The Gold Standard in Long-Shaft Portability
The Tohatsu MFS9.8CL (MPN: MFS9.8CL) redefined what boaters expect from a portable motor. While most 10hp outboards are cumbersome to lift, Tohatsu’s engineering team successfully stripped away excess weight without sacrificing internal durability. This 20-inch long shaft version is specifically optimized for vessels with higher transoms, ensuring the propeller maintains a constant "bite" in the water even in rolling conditions. It is widely considered the best power-to-weight engine for small sailboats and utility craft.
Featuring a front-mounted shift lever, the MFS9.8CL offers industry-leading ergonomics for quick and intuitive gear selection. The through-the-propeller hub exhaust system directs noise and fumes underwater, providing a whisper-quiet experience that enhances your time on the water. With digital CD ignition for fast, reliable manual starts and Tohatsu’s renowned fuel efficiency, this motor is built for the long haul.
