The Tohatsu MFS140AWETCUL represents the pinnacle of 4-stroke outboard engineering, delivering superior 140 horsepower performance through Tohatsu’s revolutionary industry-first 4-2-1 Performance Tuned Exhaust system. This advanced counter-rotation model features a sophisticated 4-cylinder SOHC-4V design with 121.6 cubic inches of displacement, operating smoothly across its 5,150-5,850 RPM range while providing the best-in-class torque-to-displacement ratio that creates excellent performance for all styles of boats from light to heavyweight applications.
Specifically engineered for twin-engine installations, the counter-rotation propeller system delivers improved maneuverability and stability, making it ideal for boats requiring balanced power distribution and enhanced handling characteristics. The sleek Beluga White finish provides an attractive, professional appearance that complements any vessel’s aesthetics, while the ultra-long 25-inch shaft accommodates deeper transom installations and larger boat applications.
The MFS140AWETCUL incorporates Tohatsu’s unique SOHC-4V design where spark plugs are strategically placed in the center of each combustion chamber for the most efficient combustion with optimal heat conduction, resulting in strong running performance and exceptional fuel efficiency. The innovative 4-2-1 Performance Tuned Exhaust manifold maximizes low-end torque and acceleration, enabling this 140hp engine to perform similarly to heavier 150hp outboards that weigh as much as 100 pounds more.
Advanced features include adjustable trolling speed control (650-850 RPM in 5 steps), accessible through the key switch on your remote control box, plus Tohatsu’s Maximum Acceleration System that improves acceleration and enhances hole shots for quicker planing performance. The fine-tuned ECU programming recognizes wide-open throttle inputs and optimizes ignition timing and fuel delivery across all four cylinders simultaneously for superior acceleration and torque delivery.
Electric start ensures reliable operation in all conditions, while integrated power trim and tilt provides effortless engine positioning and optimal performance tuning. The high-output alternator (12V, 492W, 41A) reliably powers onboard electronics and accessories, while TOCS communication system compatibility enables seamless integration with modern marine instrumentation for comprehensive engine monitoring.
Meeting California CARB 3-star rating for ultra-low emissions, the MFS140AWETCUL demonstrates Tohatsu’s commitment to environmental responsibility without compromising the outstanding torque, increased durability, and smooth operation that defines this newest model. Backed by Tohatsu’s industry-leading 5-year limited warranty and supported by decades of Japanese marine engineering excellence, the MFS140AWETCUL delivers the perfect combination of power, efficiency, and reliability that serious boaters expect from their Tohatsu 140 HP outboard.
