Ultimate Performance: No outboard gets from zero to wide-open quicker than a Mercury Pro XS with 4.6L V8 and 3.4L V6 muscle. 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 and V6 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.
