Mercury 90EXLPT 90HP Command Thrust 4-Stroke 25″ Outboard Motor

Mercury 90HP 90EXLPT Command Thrust Extra Long

Featuring a 2.1L four-cylinder engine family, the Mercury 90HP 90EXLPT 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 Command Thrust (CT) gearcase and a larger propeller diameter to maximize mechanical efficiency and hole-shot density for high-transom fiberglass skiffs and commercial barges. The 25-inch extra-long shaft design provides an optimized center of gravity for deeper draft hulls, while the Electronic Fuel Injection (EFI) and electric start ensure immediate, reliable ignition across diverse marine environments.

Operational longevity of the 90EXLPT model is secured through a specialized pressurized lubrication system featuring a maintenance-free valve train to maintain internal cleanliness. To facilitate easy after-storage starts, the unit employs a sophisticated EFI system paired with a 35A high-output alternator for accessory maintenance, while the Mercury XK360 alloy science utilizes a multi-layer finish to mitigate oxidation in high-salinity waters. With a 3-year/300-hour service interval and specialized vertical reach, this fuel-efficient outboard provides superior ownership value for professionals and recreational boaters seeking high-thrust performance.
