FourStroke 100 EFI: Peace and Quiet Is Part of The Package

More pure pleasure than ever

Mariner’s 80, 100 and 115hp mid-range Four-Strokes simply build on the awesome reputation of the previous 1.6L range. All the established advantages of the fuel-efficient EFI system are retained, but now with even greater long-term reliability achieved by sharing engine architecture with the supercharged Verado outboards. The effortless power supply is smoother and quieter than ever, thanks to the rigid engine and use of acoustic foam within the re-styled cowl. It all adds up to even greater enjoyment on the water.
