🔍 Model Background

The Mercury Mariner 115 HP EFI 4-stroke outboard (2001–2006) was part of Mercury’s early push into electronically controlled 4-stroke marine engines, designed to meet evolving emissions standards without sacrificing reliability or performance. Based on a lightweight and compact inline-4 block, this model delivered strong torque, quiet operation, and impressive fuel efficiency for its class.

Equipped with a PCM-controlled Electronic Fuel Injection (EFI) system, the 115 EFI provided quick starts, consistent throttle response, and cleaner combustion across all RPM ranges. The engine featured SmartCraft compatibility, advanced ignition timing, corrosion-resistant internals, and a maintenance-friendly layout that made it a favorite among recreational boaters and light commercial users alike.

Popular on pontoons, center consoles, and freshwater fishing rigs, the 115 EFI 4-stroke balanced smooth performance and mechanical simplicity, earning it a reputation as one of Mercury’s most dependable mid-range 4-stroke outboards during the early 2000s.
