Mercury 300HP 300L Verado V8 (DTS, 20″ Shaft)

Mercury 300HP 300L DTS V8 FourStroke Long

Featuring a 4.6L V8 engine family, the Mercury 300HP 300L serves as a high-torque solution for US boaters requiring a prop-rated propulsion unit with superior thermal stability. This 300HP four-stroke technology utilizes a large-displacement, naturally aspirated architecture to maximize hole-shot performance, effectively converting internal combustion into efficient thrust for high-performance fiberglass bass boats and coastal skiffs. The 20-inch long shaft design provides an optimized center of gravity, while the Digital Throttle and Shift (DTS) ensures immediate, reliable ignition and smooth gear transitions across diverse inland and coastal environments.

Operational longevity of the 300L 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 multi-port Electronic Fuel Injection (EFI) system paired with an 85A high-output alternator for heavy 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 class-leading weight efficiency, this fuel-efficient outboard provides superior ownership value for boaters seeking professional-grade displacement and refined torque.
