Mercury 8 HP Outboard for Sale: 8MH, 8MLH, 8EH and 8ELH

The Mercury 8 marks the step from single cylinder portables to a smoother twin cylinder engine. It shares its platform with the Mercury 9.9, so it benefits from a strong, proven design, while its 8 HP rating suits boats and waters where that is the right size. It is also available with electric start, which is rare at this power level. Here is every Mercury 8 HP outboard for sale in our stock.

Who Is the Mercury 8 For?

  • Inflatables and RIBs of about 3 to 3.5 metres.
  • Small aluminium boats and punts on lakes and rivers.
  • Sailboats of around 6 to 8 metres, with the long shaft versions.
  • Owners who need a smooth, quiet motor for trolling and slow cruising.

Why Choose a Mercury 8?

Twin cylinder smoothness

Two cylinders run with less vibration and a quieter idle than a single, which matters when trolling or motoring for long periods.

Electric start option

The 8EH and 8ELH start at the push of a button and can charge a battery, ideal for sailboats with an electrical system or for owners who find pull starting difficult.

Shared design with the 9.9

Parts and accessories are shared with the 9.9, making service straightforward.

Manual or Electric Start?

Manual start keeps the motor lighter, simpler and independent of a battery. Electric start adds convenience and battery charging but needs a battery and wiring. Many sailors choose electric start because the motor is often mounted on a bracket where pull starting is awkward.

Short or Long Shaft?

About 15 inches of transom calls for the short shaft; about 20 inches calls for L. On sailboats, choose the long shaft to keep the prop submerged when the stern lifts.

8 HP or 9.9 HP?

The Mercury 9.9 looks and weighs about the same, with more power and extra versions such as Command Thrust and ProKicker. Choose the 8 if your boat or local rules limit you to 8 HP or to save a little; choose the 9.9 otherwise.

Care Tips

  • Flush after salt water use.
  • Change engine oil and gear oil on schedule.
  • Inspect the water pump, anode, plugs and prop.
  • On electric start models, keep the battery charged and terminals clean.
