Mercury FourStroke 20hp EFI 15in Short Shaft Tiller Outboard Motor

From the second you hit the start to the moment you open it right up, EFI on Mercury outboards dishes out instant, reliable power. Cold mornings, hot arvos — doesn’t matter. You get smooth starts, crisp acceleration, and a whole lot of fun every time you hit the throttle.

Head out without lugging around a cranking battery. Battery-free EFI on manual-start models gives you confident, reliable starting and the freedom to stay lightweight and portable — perfect for exploring new water.

Built to take on the harshest marine conditions, Mercury FourStroke outboards come armed with corrosion-fighting tech from top to bottom. We’re talking advanced alloys, tough-as-nails protective coatings, sealed electronics to keep the nasties out, and an easy freshwater flush system to rinse everything clean after a big day on the water. Premium protection that keeps your motor running stronger for longer.

Set it up your way. Mercury’s adjustable tiller puts all the controls right where you need them, with options for left- or right-handed operation on select models. Comfortable, natural steering that keeps you in charge of every adventure.

Lightweight, simple to mount, and built for fun. Mercury’s 2.5–20hp four-stroke range lets you take the good times anywhere — from the tinny on the river to the tender behind the cruiser.

Mercury makes the upkeep easy as. A no-spill oil change system, easy-out fuel filter, and a lifetime maintenance-free valve train all help keep you on the water longer and out of the shed.

When you purchase a brand-new Mercury Outboard from an authorised dealer, you’re covered by a massive 3+3 year warranty. That includes a bonus extra 3 years, factory-backed, with the same comprehensive coverage as Mercury’s standard 3-year manufacturer’s warranty — labour excluded — for any failures caused by defects in materials or workmanship. And good news: if you pass the motor on, any unexpired warranty can be transferred to the next owner as long as the product is properly re-registered.

Bonus Warranty Conditions

• The dealer must complete and document the official Mercury Marine pre-delivery inspection. Warranty only kicks in once the dealer has correctly registered your outboard.
• All servicing, maintenance, and repairs must be carried out by a factory-authorised Mercury dealer, and logged with Mercury.
• Stick to the recommended service intervals and maintenance schedule from the date of purchase.
• Only use genuine Mercury parts, oils, and lubricants.
• Make sure each service is recorded in your logbook and registered online by your authorised dealer.

Maintenance Schedule

3 months from date of sale or 20 hours for use - whichever occurs first. This post sale inspection will ensure everything is operating as required on your new engine. Even if your engine has only been used for a few hours, it is important to get this inspection done by the due date.

Once a year or every 100 hours of use - whichever occurs first.
