Ultimate Performance: No outboard gets from zero to wide-open quicker than a Mercury Pro XS with 4.6L V8. This is performance that will rocket your rig out of the hole and to the next hot spot in an instant.
Tournament-Winning Torque: More displacement delivers more torque and Transient Spark technology optimizes spark timing to boost that torque during hole shot.
Squeezing Speed from Fuel: Mercury V8 Pro XS models transform every drop of fuel into performance to deliver excellent economy at cruising speed and wide-open throttle.
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.
