The Tohatsu MFS9.8CEFTUL represents the pinnacle of small outboard innovation, featuring revolutionary battery-less Electronic Fuel Injection that delivers precise fuel management without requiring a separate battery system. This sophisticated two-cylinder, four-stroke engine produces 9.8 horsepower with exceptional efficiency, consuming just 1.05 gallons per hour at wide-open throttle while maintaining smooth, quiet operation throughout its 5,300-6,200 RPM range.
Electric start convenience eliminates manual pulling, providing reliable ignition with simple push-button operation. The tiller steering configuration puts complete control directly in your hands, featuring intuitive throttle and gear controls integrated into the ergonomic handle design. The integrated power trim & tilt system allows precise boat attitude adjustment directly from the tiller handle, enabling optimal performance for varying load conditions and shallow water navigation.
With its 25-inch shaft length, the MFS9.8CEFTUL accommodates higher transom boats, pontoons, and specialty applications where extended clearance is essential. At 109 pounds, this engine balances premium features with manageable weight for installation and maintenance. The compact 12.8 cubic inches of displacement from its twin-cylinder design provides excellent power-to-weight ratio with minimal vibration.
Advanced engineering features include a 2.08:1 gear reduction ratio for optimal thrust characteristics and an 84-watt alternator that keeps onboard electronics charged during extended trips. The trochoid pump lubrication system ensures consistent oil circulation, while electronically advanced ignition timing optimizes performance and fuel efficiency across all operating conditions. EPA and CARB 3-Star emissions compliance demonstrates environmental responsibility without compromising performance.
The groundbreaking battery-less EFI technology eliminates complexity associated with traditional fuel injection systems while providing superior throttle response and fuel economy. This innovation represents Tohatsu’s commitment to making advanced fuel injection accessible in smaller displacement engines.
Perfect for pontoons, higher-transom fishing boats, and specialty watercraft requiring extended shaft length and direct tiller control with power trim convenience, the MFS9.8CEFTUL excels where precise maneuvering and premium features are paramount. Whether you’re navigating shallow backwaters, operating from elevated transoms, or requiring the ultimate in boat control, this engine delivers exceptional performance with the innovation and quality that has made Tohatsu the trusted choice for discerning boaters worldwide since 1956.
