6 HP with Tiller Handle and Manual Start on a 15 in Transom
The Suzuki DF6AS5 is a 138 cc single-cylinder four-stroke outboard rated at 6 hp across a 4750-5750 rpm full-throttle operating range, the tiller-handle, manual-start build of Suzuki’s DF6A, in the Portable range that runs from 2.5 to 30 hp. Suzuki builds it around a set of named technologies: a forced lubrication system with an additional oil passage, an offset crankshaft, three-way storage and a redesigned tiller handle.
Powerful and efficient. The 138 cc single-cylinder powerhead runs a forced lubrication system with an additional oil passage to the upper and lower crankshaft and the connecting rod big end. Positioning the crankshaft slightly off center of the cylinder reduces lateral pressure against the cylinder wall.
Easy to live with. The DF6AS5 is built as a tiller handle model with manual trim and tilt on a 15 in transom. A recoil starter turns it over, and it weighs 55 lb dry. Suzuki rebuilt the fuel and lubricating systems so the outboard can be laid down for storage on any of three sides, and reworked the tiller handle to cut the vibration that causes fatigue. A silencer shaped around the air intake keeps the noise level low.
Built for saltwater. Rounded carrying handles are built in for two-handed lifting, and the tilt system locks in five raised positions. The charging system is available as an option for keeping a battery topped up.

Rigging. This is one specific build of the DF6A, not the model line. Suzuki’s model codes read left to right from the horsepower, with T for power tilt, H for a tiller handle, and S, L or X for a 15, 20 or 25 in transom, so a tiller handle model with manual trim and tilt on a 15 in transom reads THL.
