Product Info
Lightweight, responsive, and packed with innovation, the Mercury FourStroke 15hp EFI 15" Short Shaft Tiller Outboard Motor delivers best-in-class performance for small boats, tinnies, and inflatables. Weighing 12% less than the previous model, this motor combines clever engineering with user-friendly features to make every trip smoother, quieter, and more comfortable. A refined crankshaft, drivetrain, and mid-section design help reduce overall weight while cutting vibration by up to 30%, giving you steadier control and a more enjoyable ride.
Power comes from Mercury’s robust 333cc twin-cylinder FourStroke engine, built with a low-friction SOHC design and oversized intake valves for strong torque and efficient performance. The decompression relief system ensures effortless manual starting, while the battery-free EFI system automatically manages fuel delivery and ignition timing to deliver smooth acceleration and reliable power—no battery or choke required.
The ambidextrous tiller handle sets a new standard for comfort and control. Center-mounted for balance and versatility, it offers adjustable height and angle, reversible throttle grip, and a forward shift lever that makes operation intuitive whether you’re right- or left-handed. The two-stage rubber motor mount system further enhances comfort by isolating engine vibration and reducing feedback through the tiller handle.
Mercury’s Engine Guardian system continuously monitors key operating conditions such as temperature, oil pressure, and RPM, providing audible and visual alerts—and automatic power reduction—to prevent damage and maintain performance. Maintenance is simple too, thanks to a service decal on the air silencer cover showing 100- and 300-hour service intervals and a QR code that links straight to Mercury Marine’s maintenance page.
Keeping your motor in top shape is easy with the built-in freshwater flush port, allowing you to connect a garden hose and clear out salt and debris without removing the cowling. Designed for durability and everyday usability, this 15hp FourStroke combines lightweight portability with the muscle and reliability Mercury is known for. Backed by a 3+3 non-declining warranty, it’s the ultimate small-engine upgrade—refined, rugged, and ready to perform wherever the water takes you.

Product Overview
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.
Battery-free EFIHead 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.
Corrosion ResistanceBuilt 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.
Advanced tillerSet 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.
Easy portabilityLightweight, 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.
Convenient MaintenanceMercury 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.
Mercury 3 + 3 = 6 year warranty
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.
