Mercury 300CXXL 300HP Verado V8 Counter 30″ Outboard Motor

Mercury 300HP 300CXXL Verado V8 Counter Power

Featuring a 4.6L V8 engine family, the Mercury 300HP 300CXXL 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 counter-rotating gearcase architecture and naturally aspirated V8 displacement to maximize mechanical efficiency and torque density for large multi-engine offshore vessels. The 30-inch ultra-long shaft design provides an optimized center of gravity for extreme transom heights, while the Digital Throttle and Shift (DTS) ensures immediate, reliable ignition across diverse marine environments.

Operational longevity of the 300CXXL Verado 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 performance-tuned 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 industry-leading vibration dampening via the AMS, this fuel-efficient outboard provides superior ownership value for boaters seeking professional-grade displacement and refined multi-engine synchronization.
