New Mercury 300 Pro XS FourStroke Outboard — 300HP V8

Condition report

New engine in showroom condition, photographed on the floor exactly as offered. Contact us to confirm shaft length and rigging for your transom.

Overview

The Mercury Pro XS is the motor tournament anglers swear by — and this 300 is pure Pro XS: a 4.6L V8 FourStroke built for brutal hole shots, blistering top end, and the kind of throttle response that pins you to the leaning post.

Finished in Mercury's signature black with the red Pro XS accent stripe, this engine is in showroom condition, photographed on the floor. If you're repowering a bass boat, bay boat, or offshore center console, the 300 Pro XS is the benchmark everything else is measured against.

What’s included

Included equipment is confirmed per unit at the time of inquiry — contact our team for the full list with this SKU.

Ideal for

Bass boats, bay boats, and offshore center consoles where hole shot and top-end speed decide the day.

Compatibility notes

• Confirm your boat’s capacity plate: never exceed the maximum rated horsepower.
• Match shaft length to your transom height so the anti-ventilation plate runs at the correct depth.
• Confirm your transom and hull can support the engine’s weight.
• Controls, cables, gauges, steering components, and propellers are not included unless the listing states otherwise — we verify rigging compatibility with your boat before you buy.
