Tohatsu MFS80AJETETUL 80HP – Jet 25″ Shaft Tiller or Remote

Tohatsu MFS80AJETETUL 80HP FourStroke Jet Drive

The Tohatsu MFS80AJETETUL is a high-authority 80HP Jet Drive outboard engineered for high-transom vessels operating in extreme shallow-water environments. Built on a robust 2.0L inline 4-cylinder 16-valve SOHC architecture and weighing 412 lbs, this unit delivers massive displacement and torque to the jet pump system. This 25-inch transom height model is the premier choice for large aluminum river boats and offshore skiffs requiring advanced marine propulsion units to navigate over rock-strewn rapids and sandbars without the mechanical risk of propeller damage or gearcase failure in the North American maritime sector.

Peak operational performance occurs between 5000 and 6000 RPM, translating the 2.0L energy into high-velocity water thrust through the intake grate for immediate throttle response. The direct 1.00:1 drive ratio ensures rapid hull planing and exceptional directional stability in turbulent river currents. This engine exemplifies Japanese engineering excellence, featuring NMEA 2000 connectivity and a corrosion-resistant Indigo Blue finish that resists abrasive silt-laden environments while maintaining maximum thermal efficiency for professional maritime use.

Technical Specifications of Tohatsu MFS80A Jet

• The 2.0L inline 4-cylinder SOHC powerhead provides massive displacement for superior torque and jet pump water-flow efficiency.
• Direct Jet Drive propulsion eliminates the propeller and lower unit gearcase, facilitating safe navigation in mere inches of water depth.
• The 25-inch transom height ensures proper intake positioning for high-transom offshore hulls and large aluminum river boats.
• A robust 35 Amp alternator delivers essential charging power to support modern navigation displays, fishfinders, and safety electronics.
• Electronic Fuel Injection (EFI) ensures reliable zero-choke starting and exceptional fuel economy in all maritime weather conditions.
• NMEA 2000 certification allows for seamless digital integration with on-board displays for real-time engine data and integrity monitoring.

High-Displacement Jet Authority

The FourStroke EFI Jet technology leverages its 2000cc architecture to produce industry-leading water thrust. This sophisticated design ensures the engine works efficiently at cruising speeds, providing the mechanical strength required for pushing heavy aluminum river boats through unpredictable rapids while maintaining reliable marine motor systems standards for professional shallow-water captains across North America.

Precision Fuel Induction

The Electronic Fuel Injection system monitors atmospheric variables to provide the perfect combustion ratio for maximum energy release. This advanced technology guarantees instant starting and prevents engine bogging, completely eliminating carburetor-related maintenance while providing rapid acceleration and clean combustion for long-range trips in demanding river and coastal environments across the United States.

Tohatsu 5-Year Warranty

Every Tohatsu MFS80A Jet is backed by a comprehensive 5-Year Limited Warranty for American boat owners. This industry-leading protection covers the specialized jet propulsion system and mechanical components, ensuring access to certified technicians through a vast nationwide dealer network, reflecting a deep commitment to long-term maritime reliability.

Maintenance & Longevity

Maintaining the jet intake grate and impeller clearance is vital for preserving performance. Freshwater flushing after every excursion prevents internal salt deposits and maintains cooling health. Pro Tip from the Shop: Periodically inspect the jet pump impeller for dings caused by gravel ingestion and grease the shift linkage to ensure smooth directional water flow control during harbor maneuvers.
