Features
  • Lightweight: Weighing just 38 and 57 pounds, respectively, our 2.5 - 3.5hp and 4 - 6hp FourStroke outboards are easy to lift and carry.
  • Generate Power: Convenience and performance you can count on. 4 amp alternator to charge a battery: exhaust relief holes and 6" prop for improved handling when reversing heavy boats; even an added rectifier to power small external lights. A 5hp FourStroke that powers your boat.
  • Shallow Water: Multiple trim positions enhance performance and enable shallow-water operation.
  • Easy to Start: Automatic decompression bleeds off cylinder pressure to reduce the pulling force required to start the engine.
  • Quiet: Through-prop exhaust on all Mercury® 4 - 6hp FourStrokes exits underwater for quiet operation.
  • Fueling Options: Mercury® 4, 5 and 6hp FourStrokes feature integral fuel tanks with an external fuel-shutoff valve, as well as a fuel-tank cap on top of the cowl. For extended range, these engines also can be connected to a remote fuel tank placed in the boat.
