Mercury 115HP 115EXLPT – EFI 4-Stroke 25in

Mercury 115HP 115EXLPT EFI 4-Stroke Extra Long

Technology focused and utilizing 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 high-displacement, low-weight design to maximize mechanical efficiency and hole-shot density for deep-V hulls and offshore skiffs. The 25-inch extra-long shaft design provides an optimized center of gravity for high-transom vessels, while the electric start and remote configuration ensure immediate, helm-based 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 computer-controlled EFI system paired with a 35A high-output alternator, 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 SmartCraft digital telemetry, this fuel-efficient outboard provides superior ownership value for boaters seeking commercial-grade durability with specialized transom reach.
