Our recently introduced line-up of MFS75-115A has expanded to 140 horsepower. With a dynamic design and sophisticated details, the MFS140A provides outstanding torque, increased durability, optimized weight and smooth operation.
Unique and industry-first 4-2-1 Performance Tuned Exhaust manifold has been designed to maximize low end torque and acceleration performance. Best in class torque to displacement ratio creates excellent performance for all styles of boats from light to heavy weight, pleasure or commercial use. On certain boat applications, the MFS140A will perform similarly when compared to heavier 150 horsepower outboards that weigh as much as 100 pounds more.
Engineered with Simpliq™ Technology, the MFS140A has a SOHC-4V design. The spark plugs are strategically placed in the center of each combustion chamber for the most efficient combustion with optimal heat conduction, which results in strong running and fuel efficiency.
With the introduction of MFS140A counter-rotation model, the combination of standard and counter rotation models provides better maneuverability and stability in twin MFS140A applications.
Standard features include:
•Variable Idle System to adjust the idle RPMs from 650 to 850, in 50 RPM increments, for better trolling control
•Low gear ratio (2.08:1) provides low end torque and better top end performance
•Fresh-water Flushing System designed to make routine flushing easier
•High Output 41 amp Alternator
The MFS140A provides top performance you can only experience with Tohatsu.
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. Movie available here
From 4-2-1 Performance Tuned Exhaust, MFS75/90/100/115 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
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.
The combination of standard and counter rotation models improves maneuverability and stability in twin MFS140 applications.
MF140 engines 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.
The TOCS (Tohatsu Onboard Communication System) 4.3 inch LCD Display connects to the CAN bus and communicates directly with the engine’s ECU. Engine data, fault codes, and alarms are displayed on the LCD display.
