Mercury 6 HP Outboard for Sale: 6MH and 6MLH

The Mercury 6 tops Mercury's family of single cylinder portables. It shares its compact, carry friendly body with the 4 and 5 HP models, but delivers the most push of the three. That makes it a favourite with inflatable owners who want to plane, yacht owners who run heavy tenders and sailors who need more authority in wind and current. Here is every Mercury 6 HP outboard for sale in our stock.

What Can a Mercury 6 Do?

  • Plane a light inflatable: with one person aboard in calm water, many 2.7 to 3.2 metre inflatables will get up on plane.
  • Carry a loaded tender: two or three people and gear at a brisk displacement speed.
  • Push a small sailboat: into a breeze and through tight marinas, especially with the long shaft 6MLH.
  • Serve as a backup motor: light enough to store aboard as a get home engine.

Key Features

Forward, neutral and reverse

A proper gearshift makes docking, anchoring and coming alongside much easier than on gearless micro motors.

Fuel flexibility

Run from the built in tank for short trips, or connect an external tank where the model allows for longer range. Check the product page.

Portable design

It is about the most power you can get before outboards become noticeably heavier, which is why so many tender owners settle on 6 HP.

Shared parts

Sharing a platform with the 4 and 5 HP keeps parts easy to find and service simple.

Short or Long Shaft?

Around 15 inches of transom calls for the 6MH. Around 20 inches, typical of sailboat brackets and some dinghies, calls for the 6MLH. If the prop sits too high, it will draw air and lose grip, especially in chop or when the stern lifts.

6 HP or 8 HP?

The Mercury 8 HP moves to a twin cylinder engine: smoother and stronger, but heavier. If you will carry the motor often, the 6 is usually the better choice. If it will stay on the boat, the 8 may suit you.

Getting the Best Performance

On an inflatable, move weight forward to help the boat climb onto plane. Set the motor's trim pin so the shaft is vertical when under way. On sailboats, tilt the motor clear of the water while sailing to reduce drag. Keep a spare shear pin or prop hub and a spare spark plug on board.

Care Tips

  • Flush after salt water use and check the cooling water stream when you start.
  • Change oil and gear oil at the intervals in the manual.
  • Use fresh fuel and stabilise or drain it before storage.
  • Carry and store the motor on the correct side.
