🔍 Model Background

The Mercury Mariner 225 EFI 3.0L Work outboard (2002–2008) was purpose-built for commercial and high-demand applications where durability, simplicity, and strong low-end torque were essential. Based on Mercury’s proven 3.0-liter V6 EFI 2-stroke powerhead, this model delivered 225 horsepower through a rugged platform designed to withstand punishing marine conditions.

Equipped with a PCM-controlled Electronic Fuel Injection (EFI) system, the 225 Work offered reliable cold starts, smoother acceleration, and improved fuel economy over earlier carbureted models. The “Work” variant featured reinforced engine mounts, stainless steel fasteners, commercial-duty trim systems, and upgraded cooling components for long service life in saltwater and commercial environments.

Ideal for patrol vessels, offshore workboats, and high-hour fishing operations, the 225 EFI Work stood out for its serviceable design, torque-rich performance, and heavy-duty construction. Built between 2002 and 2008, it remains a trusted solution for professionals who demand reliability above all else.
