🔍 Model Background

The Mercury Mariner 175 EFI 4-stroke outboard (2002–2007) was part of Mercury’s first generation of high-output 4-stroke V6 engines, delivering a quieter, cleaner-running alternative to traditional 2-strokes. Powered by a robust 3.0L V6 EFI powerhead, this model combined electronic fuel injection with 4-stroke reliability—offering smooth acceleration, strong mid-range torque, and exceptional fuel efficiency.

Featuring a PCM-controlled EFI system, the 175 EFI provided precise throttle response, quick cold starts, and reduced emissions. Designed for both freshwater and saltwater applications, it included SmartCraft compatibility, stainless steel components, and a saltwater-grade corrosion protection package.

The 175 EFI 4-stroke was widely used on bay boats, offshore fishing vessels, and larger recreational craft, earning a reputation for its balance of performance and reliability. Manufactured from 2002 through 2007, it remains a dependable choice for boaters seeking mid-range power with clean-running 4-stroke technology.
