The Tohatsu MFS150AETL outboard motor represents the pinnacle of Tohatsu’s mid-range MFS Series, delivering 150 horsepower from a lightweight, in-line 4-cylinder design built on the proven MFS140 platform. With a dry weight starting at just 393.5 lbs on 20″ models, this Tohatsu 150 HP outboard claims the lightest weight in its class and delivers a class-leading power-to-weight ratio that translates into quicker acceleration, confident handling, and efficient cruising. The 20-inch long shaft configuration provides excellent rigging versatility for bay boats, center consoles, pontoons, and a wide range of offshore craft popular with Florida boaters.
At the heart of the MFS150AETL is Tohatsu’s industry-first 4-2-1 Performance Tuned Exhaust manifold, which maximizes low-end torque and acceleration for stronger holeshots and quicker planing across light and heavy boats alike. The SOHC-4V design from Simpliq™ Technology places spark plugs strategically in the center of each combustion chamber for the most efficient combustion, while a newly installed knock sensor detects abnormal combustion and feeds back to the ECU to deliver smoother performance and outstanding fuel economy — achieving best-in-class efficiency at 2,000 RPM among competing models and the MFS140A. Electronic Fuel Injection and a low 2.08:1 gear ratio round out a powerplant engineered for both punchy acceleration and strong top-end performance.
Built for the demands of real-world boating, the MFS150AETL is loaded with reliability and convenience features. Electric start with MicroComputer Programmed ignition delivers fast, dependable starts, and the standard Power Trim and Tilt makes adjusting running angle effortless. The motor is fully compatible with remote steering systems and Tohatsu’s optional TOCS 4.3-inch LCD display, making it a clean upgrade or repower for modern helms. A high-output 12V, 492W, 41-amp alternator keeps batteries and onboard electronics charged through long days on the water.
Tohatsu’s Japanese engineering heritage shows in every detail: Sheet Molding Compound (SMC) cowlings for durability, anodized aluminum components, more than 16 sacrificial anodes for corrosion protection, a stainless steel water pump housing liner, and a built-in freshwater flushing system that simplifies post-trip rinses. Variable idle speed control adjusts trolling from 650 to 850 RPMs in 5 steps, and through-the-prop exhaust contributes to remarkably quiet operation. Counter-rotation models are also available in the 25″ ultra-long-shaft MFS150A variants for twin-engine setups requiring improved maneuverability and stability. For boaters from Florida and beyond, the Tohatsu MFS150AETL delivers the perfect blend of power, efficiency, and the legendary reliability Tohatsu has built since 1956.
