  • Electronic Fuel Injection (EFI): Precise fuel control provides smoother starts, improved acceleration, and reduced total fuel consumption.

  • Idle Charge: Delivers extra power at lower RPMs for your onboard electronics and accessories.

With Idle Charge, you’ll go farther, travel faster, and require fewer fuel dock stops.


Quality Built to Withstand Harsh Environments

Mercury Marine sets a reputation for industry-leading corrosion protection, and the 300HP L FourStroke is no exception. Some of the most notable features are:

  • Saltwater-Ready Construction: Anodized aluminum alloys and a rigorous paint process protect against harsh marine environments.

  • Advanced Cooling System: Keeps engine at maximum temperatures under heavy loads.

  • Stainless Steel Components: Long-lasting, corrosion-proof components for maximum reliability.

Whether cruising across lakes or open-water distances, this motor was built to endure.

  • Real-Time Engine Monitoring
