The Evinrude E-TEC G2 engine flush kit has been designed as an alternative, convenient way for fresh water flushing of the engine's cooling system. Designed specifically for use with the Evinrude E-TEC G2 engine range, the kit installs conveniently into the dual axis rigging centre and can be neatly tucked away, out of sight, when not in use. Quick-connect couplings snap together with ease, eliminating thread connections that can snap and seize and integrated check valves ensure correct operation. Connect to a water supply system with a standard garden hose fitting.
