Mercury FourStroke 30 HP EFI Outboard Motor 2024

Mercury 30 HP EFI 2024: Maximum Portable Power

The 2024 Mercury 30 HP EFI FourStroke is the strongest tune of Mercury’s 500cc three-cylinder platform — the flagship of the portable range. Battery-free EFI delivers instant starting with no battery required on pull-start models, triple-cylinder balance keeps it smoother and quieter than any twin, and full F-N-R gearing with power trim makes big-boat handling effortless. The multi-function tiller puts throttle, shift, and controls in one hand, while remote configurations suit console rigs. Add the no-spill oil change system and lifetime maintenance-free valve train, and it’s a complete package at the top of the 30HP outboard class.
