Tohatsu MFS90AETL 90HP 4-Stroke 20″ Shaft Outboard Motor

Tohatsu 90HP MFS90AETL EFI 4-Stroke Long Power

Technology driven and built upon a 1995cc four-cylinder engine family, the Tohatsu 90HP MFS90AETL serves as a high-torque solution for US boaters requiring a prop-rated propulsion unit with superior thermal stability. This 90HP four-stroke technology utilizes an industry-first 4-2-1 Performance Tuned Exhaust manifold to maximize low-end torque, effectively converting internal combustion into efficient thrust for high-transom fiberglass skiffs and center consoles. The 20-inch long shaft design provides an optimized center of gravity, while the electric start and motorized power trim ensure immediate, reliable ignition across diverse inland and coastal environments.

Operational longevity of the MFS90AETL model is secured through a specialized water-cooled system featuring a zinc-coated internal water passage to maintain internal cleanliness. To facilitate easy after-storage starts, the unit employs a sophisticated EFI system paired with a 492W alternator for extensive onboard electronics, while the Tohatsu High-Grade Marine Alloy utilizes a multi-layer finish to mitigate oxidation in high-salinity waters. With a 100-hour service interval and a class-leading torque-to-weight ratio, this fuel-efficient outboard provides superior ownership value for boaters seeking versatile high-performance power.
