Suzuki DF15A 4-Stroke Outboards

SUZUKI DF15A 4-Stroke Outboards

Starting a fuel-injected outboard usually requires a battery, but the Suzuki DF15A breaks that rule. It's the world's first 15 HP outboard built with battery-less Electronic Fuel Injection, so you get the easy, consistent starts EFI is known for, even after the motor has sat idle for weeks, with no battery required to fire the injectors. For boaters who want a dependable primary motor for a small craft or a trustworthy backup kicker, that reliability matters more than almost anything else on the water.

Beyond the battery-less start, the DF15A runs on Suzuki's Lean Burn Control System, which continuously fine-tunes the air-fuel mixture at cruising speed to stretch fuel range without sacrificing throttle response. The 2-cylinder, 327cc powerhead delivers smooth, quiet performance across a 5,000 to 6,000 RPM operating range, and Suzuki's anti-corrosion finish keeps it protected through repeated exposure to salt or fresh water.

The DF15A ships in several configurations built around the same core engine, with manual or electric start, 15" or 20" shaft lengths, and an optional power tilt setup for larger boats. Pick the version that matches your transom and rigging above; every configuration is backed by Suzuki's 5-Year Limited Warranty for recreational use.
