Product Video:

This Five Oceans Universal Motor Flusher Dual Flow provides a way to connect their Outboard and I/O Sterndrives to a freshwater source and effectively flush out sand, salt water, sediment, seaweed and silt. The universal rectangular cups are held over the engine's intake by a spring-loaded clamp and supply freshwater from a single garden hose. The Motor Flusher can also be used to perform tune-ups and other maintenance conveniently in your driveway or shop. Flush your engine's cooling system and keep corrosion out with this premium outboard motor flusher.

Note: When left in the cooling system, saltwater can cause corrosion that can lead to expensive repairs and possible engine failure; flushing the engine with freshwater helps to combat this corrosion.
