The Suzuki DF2.5S is the smallest outboard in Suzuki’s lineup, but it impresses with its features and performance. This portable 2.5 HP engine is lightweight (only about 13.5 kg) and very well balanced, which makes it extremely easy to carry using the large built-in handle on the back of the cowling. Designed with convenience in mind, the model features a twist-grip throttle on the tiller that provides precise control from any seating position, as well as 360° steering capability. This allows you to spin the motor completely around for reverse thrust and makes maneuvering in tight spaces a breeze, without needing a separate reverse gear (the DF2.5 has Forward and Neutral gears; reversing is done by rotating the engine). The DF2.5S runs quietly and smoothly, thanks to water cooling with a thermostat that enhances durability and reduces noise. Its integrated one-liter fuel tank provides roughly an hour of full-throttle run time – plenty for most short trips – and the efficient OHV engine meets CARB 3-Star ultra-low emission standards, ensuring eco-friendly operation and permission to use on regulated lakes.
Ease of use is key for the DF2.5S. Shifting is simplified (F-N only, no separate reverse – the 360° rotation handles that). The throttle lever action is smooth, and the transom clamp offers four tilt positions to accommodate different transom angles or avoid shallow ground. The engine has a convenient oil level sight gauge on the side for a quick check before heading out. Four tilt pin settings let you adjust the engine angle for varying conditions (for example, locking the motor up partially when approaching shore). Despite its small displacement of 68cc, the DF2.5S delivers surprisingly spry acceleration on lightweight craft like rowboat dinghies, square-stern canoes, or small inflatables. It’s perfect for fishing in quiet coves or serving as an emergency/auxiliary engine on a sailboat, where it can be easily stowed when not in use.
Maintenance for the DF2.5S is minimal – the engine’s oil capacity is 0.38 L, which can be changed easily via the drain plug. The motor itself is engineered for reliability with a minimalistic ignition system (digital CDI with no points). Suzuki applied high-quality anti-corrosion coatings to all aluminum surfaces, and the water pump is built tough to ensure consistent cooling flow. All of this translates to many years of trouble-free service with proper care. The DF2.5S may be small in size but it’s big on utility – a perfect companion for any boater who needs an easy-to-carry, dependable, and economical engine for short distances.
- Recommended Uses: Small inflatables, rowboats, and square-stern canoes – provides enough thrust to get around while being light enough to carry solo; excellent for powering small fishing boats on calm lakes or as a backup motor on larger boats; ideal for camping trips and remote adventures – can be hand-carried to hard-to-reach waters; highly recommended for beginners since it’s easy to handle and forgiving to operate.
