Tohatsu MFS65AJETETUL 65HP – Jet 25″ Shaft Tiller or Remote

Tohatsu MFS65AJETETUL 65HP FourStroke Jet Drive

The Tohatsu MFS65AJETETUL is a high-authority 65HP Jet Drive outboard engineered for offshore shallow-water operations on high-transom vessels where traditional propellers cannot safely navigate. Built on a robust 3-cylinder architecture and weighing 320 lbs, this unit replaces the traditional gearcase with a high-flow jet pump for superior obstacle clearance. This 25-inch transom height model is the definitive choice for aluminum river boats and offshore skiffs requiring advanced marine propulsion units to navigate over rock-strewn rapids and sandbars without mechanical risk in the North American maritime sector.

Peak operational performance is achieved between 5000 and 6000 RPM, delivering 65HP measured at the jet pump for immediate throttle response. The direct 1.00:1 drive ratio facilitates the mechanical translation of the torque curve into high-velocity water thrust, providing directional stability in turbulent river currents and tidal flows. This engine exemplifies Japanese engineering excellence, featuring a 41 Amp alternator and a corrosion-resistant Indigo Blue finish that helps support peak thermal efficiency while maintaining structural integrity in abrasive saltwater and freshwater environments.

Technical Specifications of Tohatsu MFS65A Jet

- High-output inline 3-cylinder SOHC powerhead provides reliable displacement for superior jet pump water-flow efficiency and torque.
- Direct Jet Drive propulsion eliminates the propeller and lower unit, allowing for legal and safe operation in eco-sensitive shallow-water areas.
- The 25-inch transom height helps support proper intake positioning for high-transom offshore hulls and large aluminum river boats.
- A 41 Amp alternator (492W) delivers essential charging power to support high-draw navigation systems and safety electronics.
- Electronic Fuel Injection (EFI) helps support reliable zero-choke starting and thermal efficiency in all maritime weather conditions.
- NMEA 2000 certification allows for digital integration with on-board displays for real-time engine data and integrity monitoring.

High-Transom Jet Authority

The FourStroke EFI Jet technology leverages its high-torque architecture to produce high-pressure water thrust through the intake grate. This sophisticated design helps support the engine works efficiently at cruising speeds, providing the mechanical strength required for pushing heavy 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 appropriate combustion ratio for maximum energy release. This technology is designed to support instant starting and prevents engine bogging, completely eliminating carburetor-related maintenance while providing rapid acceleration and clean combustion for long-range trips in marine river and coastal environments across the United States.

Tohatsu 5-Year Warranty

Every Tohatsu MFS65A Jet is backed by a comprehensive 5-Year Limited Warranty for American boat owners. This high-pressure 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 in thin water. Freshwater flushing after every excursion prevents internal salt deposits and maintains cooling system health.Maintenance note: Follow the manufacturer’s service procedures and lubrication specifications for the engine and gearcase.
