Tohatsu MFS90AETUL 90HP 30″ Ultra Long Outboard Motor

Tohatsu 90HP MFS90AETUL EFI Ultra Long Power

Technology focused and utilizing a 1995cc four-cylinder engine family, the Tohatsu 90HP MFS90AETUL 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 a performance-tuned SOHC architecture and specialized ultra-long gearcase to maximize mechanical efficiency on deep-transom vessels and commercial hulls. The 30-inch ultra-long shaft design provides an optimized center of gravity for high-freeboard brackets, while the electric start and motorized power trim ensure immediate, reliable ignition across diverse inland and coastal environments.

Operational longevity of the MFS90AETUL model is secured through a specialized pressurized lubrication system featuring an integrated fuel-water separator to maintain internal cleanliness. To facilitate easy after-storage starts, the unit employs a sophisticated EFI system paired with a 41A high-output alternator for 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 high-thrust propeller options, this fuel-efficient outboard provides superior ownership value for boaters seeking a reliable, low-emission engine with extreme vertical reach.
