Description
Mercury Pro XS 250hp Outboard Engine
TorqueMaster gearcase
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
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
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.
Extra charging power
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.
Performance-tuned exhaust
The exhaust tone has been fine-tuned to provide a brawny performance-inspired sound quality that is unmistakable on the water yet quieter than competing high-output engines.
Pro XS performance data
Unmatched power and speed
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.
Superior fuel economy
Advanced Range Optimisation improves cruise-speed fuel efficiency by automatically adjusting fuel delivery so seamlessly the operator won’t feel or hear it.
Lightweight heavyweight
4.6L V8 and 3.4L V6 Pro XS outboards offer a combination of ample torque and less weight – ideal for heavier loaded boats.
Pro XS advantages
Efficient all-around performance
A host of efficiency-enhancing features such as Advanced Range Optimisation (ARO), a closed-loop fuel system and a hydrodynamic gearcase optimise fuel economy so you can get more done on every tank.
Squeezing speed from fuel
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.
Tournament-winning torque
More displacement delivers more torque and transient spark technology optimises spark timing to boost that torque during hole shot.
Smart charging
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.
