Mercury Joystick Piloting technology is now available for the popular Mercury Racing 520 sterndrive. The naturally aspirated engine provides recreational boaters a cost effective power option that fits nicely, in both value and performance, between the MerCruiser 8.2L MAG HO and Mercury Racing 540. The low-cost sterndrive engine features digital throttle and shift (DTS) and of course is backed by an unprecedented two-year limited factory warranty. Joystick Piloting will be available on select 520 models featuring Mercury Racing Bravo Three XR drives.
