🔍 Model Background

The Suzuki 25 HP 4-stroke outboard (2014–2024), part of the DF25A series, is a class-leading portable engine designed for lightweight fishing boats, inflatables, tenders, and skiffs. Combining exceptional fuel efficiency, smooth throttle response, and ultra-low emissions, it quickly became a go-to choice for boaters who prioritize portability without sacrificing performance.

This model features a 3-cylinder DOHC engine with advanced electronic fuel injection (EFI)—offered in both manual and electric start options and capable of battery-less EFI operation for easier rigging and maintenance. Suzuki’s Lean Burn Control System and offset driveshaft design further improve efficiency, weight balance, and engine compactness.

Weighing under 140 lbs, the DF25A is one of the lightest EFI-equipped 25 HP outboards in its class. Available in short and long shaft versions with tiller or remote steering, it offers broad versatility for both recreational and utility use in freshwater and coastal environments.

Produced from 2014 through 2024, the Suzuki 25 HP DF25A remains a standout choice for boaters seeking modern 4-stroke performance, unmatched fuel economy, and easy-to-transport reliability.
