🔍 Model Background

The Mercury 175 HP XRI outboard (1999–2004) was part of Mercury’s proven 2.5L V6 EFI 2-stroke lineup, with the “XRI” designation indicating it was equipped with Electronic Fuel Injection (EFI) for improved throttle response, fuel atomization, and overall performance. These engines bridged the gap between traditional carbureted 2-strokes and newer DFI systems like OptiMax, offering strong acceleration and relatively simple maintenance.

The 175 XRI was especially popular among bass boaters, tournament anglers, and recreational offshore users looking for a lightweight yet powerful outboard with crisp throttle delivery. With features like oil injection, CDM ignition, and a mechanically governed fuel system, it offered excellent midrange torque, straightforward rigging, and long-term reliability when properly maintained.

Although it was eventually phased out in favor of cleaner-burning DFI and 4-stroke models, the 1999–2004 175 XRI remains a respected workhorse with readily available parts, strong aftermarket support, and a dedicated following in the freshwater and saltwater fishing communities.
