2017 Tohatsu 20 HP MFS20DEFS Outboard Motor: Performance Meets Reliability

The 2017 Tohatsu 20 HP MFS20DEFS outboard motor is engineered to deliver robust performance, reliability, and ease of use. Designed specifically for medium to larger aluminum fishing boats, skiffs, inflatables, and heavier sailboats, this motor is versatile and dependable. With a 15-inch shaft and tiller steering, it offers flexibility, including both electric and manual start options, catering to various user preferences and operating environments.

Unmatched Power and Efficiency

Powered by a 2-cylinder, 351 cc engine, the Tohatsu MFS20DEFS produces a consistent 20 horsepower, making it suitable for a wide range of marine applications. Its carburetor fuel delivery system combined with an advanced digital CD ignition system ensures efficient fuel combustion, smooth acceleration, and reliable starts. This motor’s ability to run on unleaded gasoline (87 octane) makes refueling simple and accessible worldwide.

Durable Construction and Marine-Grade Materials

Constructed with high-grade marine alloy, this outboard motor is built to withstand harsh marine conditions. The stainless steel water pump housing and zinc-coated water passages provide corrosion resistance, extending the engine’s lifespan, especially in saltwater environments. Additionally, sacrificial zinc anodes and trim tabs help protect the engine components from corrosion, further enhancing durability.

User-Friendly Features for Convenience and Safety

Operating the MFS20DEFS is intuitive thanks to features like the forward-mounted gear shift lever and twist-grip throttle with adjustable tension control. The motor includes a low oil pressure warning system and an ESG over-rev RPM limiter that protects the engine from damage during operation. A safety lanyard cut-off switch adds an extra layer of safety, immediately stopping the motor in case of an emergency.

The tiller steering includes an adjustable friction setting, allowing for smoother control and maneuverability on the water. Additionally, the motor’s thermostatically controlled cooling system ensures optimal operating temperature, reducing wear and increasing efficiency.

Comprehensive Package with Warranty

When purchasing the 2017 Tohatsu 20 HP MFS20DEFS, you receive a full package, including a 3.1-gallon external fuel tank with a quick connect fuel line, a 9.2” diameter 3-blade aluminum propeller, an owner’s manual, and a tool kit for basic maintenance. The product is backed by a Tohatsu 5-year warranty, providing peace of mind and ensuring you invest in a reliable marine engine.
