Product Info
Reliable power, easy handling, and compact design come together in the Mercury FourStroke 3.5hp 20" Long Shaft Tiller Outboard Motor. Ideal for sailboats, tenders, and small craft that need a little extra reach, this outboard’s long shaft delivers smooth propulsion and enhanced control — all from a portable 18kg package. Built with the same precision engineering found across Mercury’s range, it’s lightweight, durable, and simple to carry or mount using the integrated handles and lifting points.
The long tiller handle and twist-grip throttle make steering and throttle response effortless, while Forward and Neutral shifting with 180° steering and full-thrust reverse give you confident control in tight spots. Whether you’re docking, drifting, or exploring calm waters, this setup makes every trip simple and stress-free. The four-point mounting system keeps vibration low and performance steady across the rev range, while the built-in 1L fuel tank keeps your setup compact and clutter-free. The external shutoff valve also allows you to run the carburettor dry before storage — a small feature that goes a long way in maintaining reliability and extending engine life.
Starting the engine is quick and straightforward, with a Capacitor Discharge (CD) ignition system and decompression design that make pull-starts smooth and consistent. Maintenance is equally simple, thanks to an easy-view oil gauge, accessible drain plug, and vented fuel cap that help prevent spills and make oil checks fuss-free. With four manual trim positions, you can easily fine-tune performance to suit conditions or lift the motor clear of the water when beaching or trailering.
Backed by Mercury’s trusted 3+3 non-declining warranty, this compact FourStroke offers dependable power and easy operation for any on-water adventure. It’s portable, practical, and purpose-built for boaters who want maximum control without the weight.

Product Overview
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.
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.
Maintenance Schedule
First 3 Month Inspection3 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.
Annual InspectionOnce a year or every 100 hours of use - whichever occurs first.
