Mercury 300XL 300HP Verado V8 25″ Shaft Outboard Motor

Mercury 300HP 300XL Verado V8 Long Power

Technology driven and built upon a 4.6L V8 engine family, the Mercury 300HP 300XL Verado serves as a high-torque solution for US offshore boaters requiring a prop-rated propulsion unit with superior thermal stability. This 300HP four-stroke technology utilizes a naturally aspirated 8-cylinder architecture and Advanced MidSection (AMS) to maximize mechanical efficiency and torque density for premium center consoles and offshore skiffs. The 25-inch extra-long shaft design provides an optimized center of gravity, while the Digital Throttle and Shift (DTS) ensures immediate, reliable ignition across diverse inland and coastal environments.

Operational longevity of the 300XL Verado model is secured through a specialized pressurized lubrication system featuring high-capacity cooling to maintain internal cleanliness. To facilitate easy after-storage starts, the unit employs a sophisticated multi-port EFI system paired with a 115A 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 whisper-quiet operation, this fuel-efficient outboard provides superior ownership value for boaters seeking professional-grade displacement and unmatched refinement.
