The Suzuki DF9.9 outboard engine is one of two very similar engines in the Suzuki range, the DF8 being its little brother.
The very small built-in fuel tank is supplemented by the external 12 litre fuel tank to give a longer range. This tank and line are supplied as standard. The Suzuki DF9.9 A engine weighs in at between 40kg and 44kg, depending on the exact model.
The newest Suzuki DF9.9B model is very similar to the larger DF15A model (see separate entry). This new model of the Suzuki 9.9hp outboard engine has fuel injection.
