MFS 140

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.

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.
