Tohatsu 150HP Outboard Engine

Product Description

MFS150A

HIGH POWER

When it comes to high-horsepower outboard motors, weight still matters.
The lighter the engine, the more responsive and efficient the performance.

Designed with an optimized lightweight structure, the MFS150A delivers class-leading power-to-weight performance, translating into quicker acceleration, confident handling, and efficient operation at 150 horsepower.

With bold new styling featuring dynamic 3D side decals and a sporty rear design, the MFS150A not only looks the part.
It also 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.

Engineered with Simpliq™ Technology, the MFS150A 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 MFS150A counter-rotation model, the combination of standard and counter rotation models provides better maneuverability and stability in twin MFS150A applications.

Standard features include:

• Lightest weight in its class
• 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

Experience a new level of boating excitement with Tohatsu’s new 150 hp outboard motor.
