2026 Mercury Marine® Pro XS 300hp

Mercury Pro XS® outboards are engineered for those boaters who demand ultimate performance – anglers competing on the highly competitive tournament trails and powerboaters who simply crave speed and acceleration. Exclusive components and tuning extract every ounce of performance from each Pro XS model so you can take it to the limit

Features may include:

• The lightweight TorqueMaster gearcase (featured on select V8 models) has a 1.75:1 gear ratio and a robust 1.25-inch-diameter prop shaft designed for semi-surfacing, high-speed applications.

• Transient Spark Technology electronically adjusts the ignition timing of the engine as needed. This subtle, automatic change produces additional torque for faster hole shot and acceleration.

• Adaptive Speed Control maintains a desired rpm regardless of changes in load or conditions without adjustments to the throttle lever position – a first for the outboard industry.

• A powerful alternator provides net charging output of 20 amps at idle and 85 amps at wide open throttle. Idle Charge battery-management technology automatically increases idle rpm to boost alternator output and recharge low batteries.

• Exhaust tone has been fine-tuned to provide a brawny performance-inspired sound quality that’s unmistakable on the water yet quieter than competing high-output engines

• The V8 and V6 Pro XS outboards perform like no other, with a dual overhead cam design that delivers instantaneous throttle response and immediate power.

• Advanced Range Optimization improves cruise-speed fuel efficiency by automatically adjusting fuel delivery so seamlessly the operator won’t feel or hear it.

• 4.6L V8 and 3.4L V6 Pro XS outboards offer a combination of ample torque and less weight – ideal for heavier loaded boats

• A host of efficiency-enhancing features such as Advanced Range Optimization (ARO), a closed-loop fuel system and a hydrodynamic gearcase optimize fuel economy so you can get more done on every tank.

• Mercury V8 and V6 Pro XS models transform every drop of fuel into performance to deliver excellent economy at cruising speed and wide-open throttle.

• More displacement delivers more torque and Transient Spark technology optimizes spark timing to boost that torque during hole shot.

• A powerful alternator provides net charging output of 20 amps at idle and 85 amps at wide open throttle. Idle Charge battery-management technology automatically increases idle rpm to boost alternator output and recharge low batteries
