🔍 Model Background

The Mercury Mariner 150 HP EFI 4-stroke outboard (2002–2007) was introduced as part of Mercury’s new generation of high-performance 4-stroke engines, offering cleaner operation and improved efficiency over traditional 2-strokes. Built on a robust 3.0L V6 4-stroke powerhead, this model delivered strong torque, smooth acceleration, and low emissions — ideal for both saltwater and freshwater use.

Featuring a PCM-controlled Electronic Fuel Injection (EFI) system, the 150 EFI provided quick starts, precise fuel metering, and consistent performance in varying conditions. Corrosion-resistant components and saltwater-grade durability made it a popular choice for center consoles, bay boats, and multi-purpose recreational craft.

Produced from 2002 through 2007, the Mercury Mariner 150 EFI 4-stroke became known for its reliability, quiet operation, and ease of maintenance. It remains a solid option for boaters seeking efficient, mid-range 4-stroke power with proven Mercury engineering.
