Details & Inspection Notes
Suzuki's 4 HP DF4AS2 is a single-cylinder, carbureted portable weighing 52.0 lb, built around a 15-inch short shaft with tiller steering and manual start. It carries the Suzuki 3-year warranty.
Built to carry
A large fold-down carrying handle and a tiller handle that folds flat make this motor easy to move and stow in three positions, on the starboard side, the port side or facing forward, which matters on a small boat with limited locker space. This engine sips from a small built-in tank, giving close to three-quarters of an hour of running at full throttle before it needs more fuel, which keeps the whole package light enough to carry.
Controls and protection
A twist-grip throttle with a tension adjuster sits on the tiller alongside a large gear shift lever, and steering friction can be tightened so the motor holds a course without constant hand pressure. Shallow water drive gives two tilt positions for running in thin water, and an over-rev limiter plus an emergency lanyard stop switch add basic protection.
Built for salt water
Multi-layer corrosion protection covers the block and fittings, and the engine is rated for saltwater use, which matters for anyone running this on a coastal dinghy or small inflatable.
Can it tilt up for shallow water? Yes, shallow water drive offers two positions. How much does it weigh? 52.0 lb, light enough to carry by hand.
