The Tohatsu MFS140AWETUL represents the pinnacle of mid-range outboard engineering, combining 140 horsepower of refined 4-cylinder power with Tohatsu’s revolutionary technology and elegant Beluga White finish. This Generation A model features a robust 121.6 cubic inch, 4-cylinder engine with Single Overhead Cam design and electronic fuel injection, delivering smooth power throughout its 5,150-5,850 RPM operating range. The precision-engineered 25-inch ultra-long shaft length makes this outboard ideal for larger transoms, pontoon boats, and specialty applications requiring extended reach.
The industry-first 4-2-1 Performance Tuned Exhaust system sets this outboard apart from the competition, providing outstanding torque performance, top-end speed, acceleration, and exceptional fuel economy. This innovative exhaust design features equal-length passages for each cylinder, promoting optimal performance throughout the entire RPM range while creating extra suction to enhance exhaust flow. Combined with the unique SOHC-4V design and strategically placed spark plugs, the MFS140AWETUL delivers the best-in-class torque-to-displacement ratio that outperforms heavier 150 horsepower outboards weighing up to 100 pounds more.
The elegant Beluga White finish provides a premium appearance that complements luxury vessels and sport boats while offering enhanced UV resistance and durability. Electric start ensures reliable operation in all conditions, while the integrated power trim and tilt system provides optimal boat attitude control for maximum performance and comfort. The 25-inch ultra-long shaft configuration weighs 402 pounds, delivering exceptional power-to-weight ratio while maintaining structural integrity for demanding applications.
Advanced features include adjustable trolling speed control from 650-850 RPMs in 5-step increments, accessible through remote control systems or multi-function tiller handle options. TOCS (Tohatsu Onboard Communication System) ensures seamless integration with modern marine electronics through simple plug-and-play connections. The Maximum Acceleration System improves holeshot performance, while the Fuel-Efficient Cruise System maximizes range during extended runs.
Standard equipment includes a high-output alternator producing 12V, 492W, 41A to handle demanding electrical loads, along with comprehensive safety features including engine stop switch lanyard, overheat warning system, and diagnostic capabilities. The 2.08:1 gear reduction ratio ensures optimal propeller performance across a wide range of applications, from recreational cruising to commercial operations.
California CARB 3-star rated for ultra-low emissions and backed by Tohatsu’s industry-leading 5-year limited warranty, the MFS140AWETUL represents over 100 years of Japanese marine engineering excellence. Whether powering luxury pontoons, center console boats, or specialty vessels requiring extended shaft reach, this outboard delivers the perfect combination of power, innovation, and elegance that discerning boaters have trusted since Tohatsu’s founding in 1922.
