    Mercury 15 and 20hp FourStroke outboards come standard with a three-position choke, eliminating the need for a primer button. Starting is easier and warm-ups are faster!
  • Electrical support. – A high-output alternator keeps batteries charged and fishing electronics humming.
  • Great acceleration / more torque. – Compact but powerful, Mercury® 15 – 30hp FourStroke outboards feature extra displacement and outstanding low-end torque that put a boat smartly on plane.
