Mercury 9.9MLH EFI FourStroke^®

Manual Control with EFI Confidence

A 20-inch-long shaft makes a noticeable difference on smaller boats with deeper transoms, helping the propeller stay properly submerged for consistent handling. The Mercury 9.9MLH EFI FourStroke outboard for sale combines that longer shaft with tiller steering, manual start, and Electronic Fuel Injection (EFI) for owners who value direct control and uncomplicated operation.

Electronic Fuel Injection (EFI) eliminates the need for a manual choke. It makes cold starts easier and provides smooth, responsive performance throughout the operating range. The inline 2-cylinder powerhead operates within a 5000–6000 RPM range, while the standard gearcase delivers predictable handling for everyday boating. Manual trim with multiple ratcheting positions makes it easy to adjust the engine angle for varying loads or shallow-water operation, and the 12 L remote fuel tank supports longer outings without frequent refuelling.

This 9.9 HP Mercury outboard comes with Mercury's 5-year factory-backed limited coverage, including a 3-year standard warranty plus 2 years of Mercury Product Protection Gold.
