2025 Tohatsu MFS90 L

The MFS90 design is built on our best-selling models the MFS40/50/60 and the MFS9.9/15/20. The legacy of our top performing and most reliable engines has been passed on, with a dynamic design and sophisticated details, to our all new MFS90 4-stroke outboard with industry-first innovative feature and characteristics.

The groundbreaking industry-first technology, 4-2-1 Performance Tuned Exhaust, provides incomparable torque throughout the RPM range. The higher torque you have, the better the holeshot, which translates to faster speeds. Higher torque also means less drag, which in turn means more boating options; it could be applied to any type of boat. From light to heavy, pleasure or commercial boats.

The synergy between the 4-2-1 Performance Tuned Exhaust and our fine-tuned ECU programming, MFS90 provides a strong acceleration when needed in order to get the boat on plane quicker and allowing you to reach the top end speed faster.

Equipped with standard features such as Variable Idle System allowing you to change the idle speed from 650 to 850 RPMs, a low gear ratio (2.08:1) giving you the increased low end torque your boat needs, a fresh-water Flushing System designed to make routine flushing easier, and a High Output 41 amp Alternator, the MFS90 provides the industry leading features you expect from Tohatsu.
