FourStroke 115 EFI: The Highest Displacement Engine

Thanks to Mercury’s never-ending commitment to provide industry-leading innovation, now you can hang a lighter, more compact FourStroke outboard on your transom that delivers better performance, hole shot and towsport capability than the previous 80 - 115hp models – along with increased fuel savings, hassle-free maintenance and rugged reliability.

High Displacement / Less Weight

These FourStroke outboards displace 2.1 liters, which means they work smarter – not harder – leading to improved durability and longer life, not to mention greater hole shot, superior overall acceleration and awesome top speed.

Smooth and quiet

Sound and vibration are minimized by the tightly sealed, thermo-bonded cowl; the Idle-Relief Muffler, which utilizes an acoustic filter to reduce high-frequency exhaust noise; a new smooth clutch design; and Mercury’s exclusive Focused Mount System.

Easy to maintain

Replacing the fuel filter requires no tools and can be accomplished in less than a minute.A QR code links your cellphone to helpful “How To” videos.And thanks to Mercury’s Maintenance-Free Valve Train, you’ll never need a costly valve-lash adjustment.

Fuel efficient

Less weight combined with high displacement helps these FourStroke outboards provide maximum fuel efficiency, especially at cruising speeds.Specialized oil scrapers and bearings minimize friction in the crankshaft, also resulting in decreased fuel consumption.
