Mercury 15 HP EFI 2024: Injected Torque for Real Work

The 2024 Mercury 15 HP EFI FourStroke pairs a generous 333cc twin with electronic fuel injection — instant starts in any weather, crisp response from idle to wide open, and zero carburetor worries after storage. The multi-function tiller integrates controls in one hand, F-N-R gearing simplifies docking, and manual or electric start plus tiller or remote rigging cover every setup. With Mercury’s no-spill oil change and maintenance-free valve train, it’s a thoroughly modern fifteen in the 15HP outboard class.
