🔍 Model Background

The Mercury 30 HP 4-Stroke outboard (1999–2003) marked Mercury Marine’s transition into cleaner, quieter small-engine technology. Developed in collaboration with Yamaha, this model featured a 3-cylinder, 526cc four-stroke engine block known for its smooth operation, fuel efficiency, and low emissions — meeting increasingly strict environmental regulations of the early 2000s.

Equipped with carbureted fuel delivery, CDI ignition, and overhead cam design, the 30 HP 4-stroke delivered dependable mid-range performance for a wide range of boats including aluminum fishing rigs, small pontoons, and utility vessels. Its refined engineering resulted in noticeably quieter operation compared to its 2-stroke counterpart, making it especially attractive for trolling and recreational cruising.

This model was available in multiple shaft lengths and control options (tiller or remote), offering flexibility for various applications. While later replaced by EFI-equipped models, the 1999–2003 Mercury 30 HP 4-Stroke remains a solid choice for boaters who value quiet operation, fuel economy, and dependable all-around performance.
