Mercury 115EXLPT 115HP Command Thrust 4-Stroke 25″ Outboard Motor

Mercury 115HP 115EXLPT Command Thrust Extra Long

Featuring a 2.1L four-cylinder engine family, the Mercury 115HP 115EXLPT serves as a high-torque solution for US boaters requiring a prop-rated propulsion unit with superior thermal stability. This 115HP four-stroke technology utilizes a Command Thrust (CT) gearcase architecture and a larger internal gear set to maximize mechanical efficiency for high-transom commercial utilities and heavy pontoon boats. 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 inland and coastal environments.

Operational longevity of the 115EXLPT 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. With a 3-year/300-hour service interval and an oversized gearcase footprint, this fuel-efficient outboard provides superior ownership value for professionals seeking high-thrust performance and durability in specialized transom heights.
