🔍 Model Background

The Mercury Mariner 150 HP DFI Optimax outboard (2000–2006) was a key part of Mercury’s first-generation Direct Fuel Injection (DFI) lineup, designed to offer the benefits of traditional 2-stroke power with modern efficiency and cleaner operation. Built on a durable 2.5L V6 platform, this engine featured Mercury’s proprietary air-assisted Optimax DFI system for exceptional fuel economy and low emissions.

With precise, high-pressure fuel delivery directly into the combustion chamber, the 150 Optimax provided strong acceleration, excellent throttle response, and reduced oil consumption compared to conventional 2-stroke models. It also included SmartCraft diagnostics compatibility, a high-capacity cooling system, and solid-state ignition for reliable all-weather operation.

Widely used on bass boats, bay boats, and sport fishing rigs, the 150 Optimax gained a reputation for durability, fuel efficiency, and dependable performance. Produced from 2000 to 2006, it remains a standout choice for boaters who want proven 2-stroke power with modern engineering benefits.
