MFS8 - A New Generation of Power

The new generation of MFS8C/9.9CY(W) model lineup is engineered to be EFI (Electronic Fuel Injection) for the first time in 200cc class.

The battery-less EFI (Electronic Fuel Injection) model is the lightest 2-cylinder 8/9.9 hp on the market, with upgraded features from its predecessor.
In addition to upgrading this model to EFI (Electronic Fuel Injection), Tohatsu has applied a variety of new features.

Tohatsu 5hp 4-Stroke Benefits

  • Lightest 2-Cylinder EFI available on the market
  • 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

Easy Operation and Handling

  • Digital CD ignition for easier engine starting, quicker throttle response and smoother trolling
  • Recoil starter with larger reel making manual starting fast and easy
  • Shallow water drive
  • 6 trim positions
  • Adjustable steering friction for reducing steering effort*

Convenience and Reliability

  • Through-the-prop exhaust for a quieter ride
  • Thermostatically controlled cooling system for consistent engine temperature
  • Stainless steel water pump housing liner 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
  • 12 litre fuel tank with fuel gauge
  • Aluminum propeller

Safety & Protection

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

The very first Battery-less EFI System in 8/9.9hp.

The EFI system will provide consistent starting, stability at idle and fuel efficiency. Additionally, the EFI system will eliminate the hassles experienced with carbureted models, such as clogging and overhaul of carburetor because of ethanol fuel related issues.

Water Cooled Fuel Pump

Water cooled fuel pump is now a standard feature on MFS8C/9.9CY(W) to offer consistent starting, stable idling and optimal running.

Standard Tiller Handle

Ergonomically designed tiller handle includes forward-neutral-reverse front shift lever, stop switch, throttle friction adjustment and power tilt switch (for PT-models) for easier access and maneuverability.

Newly Designed Carrying Handle for Tiller Model

In addition to an overall cleaner look by routing shift & throttle cables and wirings through the handle, the new carrying handle features a 40% increase in surface area and smooth shape to reduce the pressure when carrying.

Easy-to-Use Flushing Port

Similar to other Tohatsu models such as MFS9.9E-MFS140A, flushing port has been relocated to the mid-section for easier access. Freshwater flushing is now easier than ever as no special tools are required.

Improved Crankcase Ventilation System

After countless testing and analysis, the returning port of the engine crankcase vent has been positioned where the vacuum pressure draws the blow-by vapors more efficiently.

Improved Center of Gravity

The center of gravity has slightly shifted toward the front of the outboard reducing the manual tilt effort by 19%.

PT Switch on Certain Models

A PT switch located on the starboard side of the outboard comes standard for remote control power tilt models. PT Switch allows for effortless tilting from outside the boat.

Easy Daily Maintenance Fuel Filter

Clear fuel filter with floating indicator ring provides detection of water in the fuel system. Tool-free quick drain valve allows for easy serviceability.
