This Five Oceans' universal outboard motor flusher provides a way for boaters to connect their outboard or inboard/outboard to a freshwater source to run the engine to effectively flush out salt water and silt.
The universal round cups are held over the engine's intake by a spring-loaded clamp and supplied freshwater from a single garden hose.
The outboard 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 at bay 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.


Removes corrosive saltwater and silt from outboard and inboard/outboard engine cooling systems

Round cups deliver freshwater from a garden hose and are held in place by a spring clamp
Allows routine maintenance or tune-ups to be performed on dry land
Can be used with inline mixers to deliver salt removal products for a more thorough flushing
