Features

Features

  • 4-2-1 PERFORMANCE TUNED EXHAUST: Isometric aggregated exhaust manifold "4-2-1 Performance Tuned Exhaust" maximizes torque and acceleration performance. This unique design is an industry-first and can only be found on Tohatsu Outboards. By engineering each exhaust passage to be equal in length, the merging of exhaust of each cylinder creates extra suction that helps pull the exhaust from the engine. This completely eliminates the possibility of exhaust interference and drastically improves the performance.
  • OUTSTANDING TORQUE: From 4-2-1 Performance Tuned Exhaust, MFS75/90/115 have the highest torque that gets you on plane quicker and reach the top end speed faster than any other competitors. **Data based on research done and collected by Tohatsu Engineering Department
  • SUPERIOR DURABILITY & OPTIMIZED WEIGHT: For high durability and weight reduction purposes, Tohatsu optimized each relatively heavy component such as cylinder head, exhaust manifold, engine base, oil pan, lower unit etc.. Also, special anodized process has been utilized on all major aluminum components for prolonged engine life.
  • EXCELLENT FUEL EFFICIENCY: MFS75/90/115 have a unique SOHC-4V design in its class where competitors are either SOHC-2V or DOHC-4V. Spark plugs are strategically placed in the center of the each combustion chamber for the most efficient combustion with optimal heat conduction which results in strong running and fuel efficiency.
  • QUIETNESS: With the even-length Intake Manifold, 4-2-1 Performance Tuned Exhaust, and fine-tuned ECU, MFS75/90/115 provide exhilarating and performance-inspired engine sound. Also within the large capacity Idle Port, sounds reflect off each other to dampen the exhaust flow which contributes to the lowest sound at idle.
  • MANEUVERABILITY: With its fined-tuned ECU programming, MFS75/90/115 are designed to improve acceleration when needed in order to get the boat to plane quicker. When you throttle to wide open, the ECU recognizes it and ignites in all four cylinders at the same time. Simultaneously, the ECU optimizes and supplies adequate air & fuel which makes air/fuel mixture more suitable for rapid acceleration to generate higher torque. The higher the torque you have, the stronger the acceleration you will get, resulting in enhanced hole shots and thus, quicker planning. Also, Upper and Lower Mounts, and the Gear Case are optimized for direct steering response & maneuverability, and greater stability.
  • MULTI-FUNCTION TILLER HANDLE WITH GRIP-END PTT SWITCH: Multi-Function Tiller Handle is a great choice for commercial use. It has an ergonomically designed large Shift Lever located at the front and a longer Throttle Grip with a PTT (Power Trim & Tilt) switch located at the grip-end for easier operation and maneuverability. To balance different wind and current conditions, the Variable Idling System allows the user to select the best idling speed from 5 different RPM ranges by simply pressing the Key Switch.
