MFS 9.8

Our first priority when developing these engines was to make them lightweight and compact without comprising reliability or the quality performance associated with the Tohatsu brand name. We have maintained the durable standard features that Tohatsu owners appreciate while making fuel-efficient 4-strokes that are easy to transport. These outboards are compact 2-cylinder, SOHC engines that have been manufactured to comply with all US EPA 2006 & CARB 2008 (3-star rating) emission regulations.

Tohatsu 4-stroke benefits:

  • Light and compact!
  • Designed with proven technology
  • Available in a wide variety of models
  • Greatly reduced vibration for smooth and stable running at all speeds
  • Greatly reduced induction noise for a quieter ride
  • Trim tab reduces steering effort, functioning also as the sacrificial anode that protects the engine from electrolysis
  • Ultra Low emission, EPA and CARB approved

High performance and easy operation:

  • Digital CD ignition for easier engine starting, quicker throttle response and smoother trolling
  • Fast-idle choke system eliminating the need for manual choke operation
  • Recoil starter with larger reel making manual starting fast and easy
  • Shallow water drive, 6 positions
  • Adjustable steering friction for reducing steering effort

Fundamentals for user convenience and reliability:

  • Through-the-prop exhaust for a quieter ride
  • Thermostatically controlled cooling system for consistent engine temperature
  • Stainless steel water pump housing for outstanding durability
  • High grade marine aluminum alloy that provides the ultimate protection against corrosion
  • Zinc coating on internal water passages for superior corrosion resistance
  • Plastic fuel tank with fuel gauge on the cap*
  • Aluminum propeller

Warnings and protection:

  • Low oil pressure indicator
  • Overheat warning (visual and audible)
  • Safety lanyard (an essential protection feature standard on all Tohatsu outboards)
  • Start-in-gear protection for safer engine starting
  • Over-rev. limiter
