Features That Make the Mercury 300HP XL Stand Out

1. Advanced Four-Stroke Power

Mercury’s four-stroke technology is the gold standard for quiet, clean, and efficient performance. The 300HP XL delivers maximum horsepower without using fuel or making noise. It is ideal for recreational boaters and commercial marine professionals.

2. Exclusive V8 4.6L Platform

The 4.6-liter V8 engine delivers a massive torque reserve, with lightning-fast acceleration and solid top-end speed. Whether you’re running supplies, fishing in the offshore, or pulling a wakeboarder, this engine won’t let you down.

3. Adaptive Speed Control (ASC)

Maintain a steady RPM even through tight turns, heavy chop, or full loads. Mercury’s ASC automatically adjusts your engine to the water conditions present for a smoother ride and better fuel efficiency.

4. Digital Throttle and Shift (DTS)

Enjoy buttery-smooth shifting with Mercury’s DTS system. The digital control system gives you precise control of your shifting and throttle — with no lag or grinding.

5. Advanced MidSection (AMS) Mounting

Reduces vibration and noise transfer to the boat. This makes the Mercury 300HP XL ideal for luxury boats and commercial vessels alike. The AMS design creates a more comfortable onboard experience for everyone.

6. Powerful Charging System

With a 115-amp alternator, you’ll never run out of power. The system is optimized for charging onboard electronics, livewell pumps, navigation equipment, and more.
