🔍 Model Background

The Mercury 30 HP 4-stroke EFI outboard (2016–2020) was part of Mercury’s new-generation compact engine lineup, designed to offer smoother performance, lower emissions, and advanced technology in a lightweight package. Built around a refined 500cc inline-3 engine platform, this model delivered reliable power for a wide range of boats, from aluminum fishing skiffs to inflatable tenders and utility craft.

Equipped with Electronic Fuel Injection (EFI), the 30 HP provided improved cold starts, better throttle response, and optimized fuel economy compared to older carbureted designs. It also featured a single overhead camshaft (SOHC), integrated fuel tank (on portable variants), and compatibility with Mercury’s SmartCraft digital systems.

With multiple shaft lengths, remote or tiller steering, and options for electric or manual start, the 2016–2020 Mercury 30 HP 4-stroke EFI was a versatile choice for both recreational and light commercial use. Known for its quiet operation and ease of maintenance, it remains a top pick among boaters looking for modern efficiency in a compact 4-stroke package.
