2022 Mercury 300XL SeaPro® Commercial
ENGINEERED FOR EXTREME RELIABILITY AND DURABILITY
Mercury has calibrated its new V8 and V6 SeaPro outboards to generate ample torque at lower rpm levels, enabaling users to work their outboards hard without placing excess stress on the engine.
HEAVY-DUTY GEARCASE
• All V8 and V6 SeaPro engines feature a heavy-duty gearcase validated at three times the lifespan of a recreational gearcase.
• The SeaPro gearcase was designed with easy maintenance in mind: oil can be easily drained from the gearcase torpedo.
