Back in the day, I guess still even to this day flushing an outboard with fresh water was done only one way. A set of "ear muffs" or "flush muffs" was fitted around the engine's gearcase to cover the water intakes, connected to a garden hose with a good water supply, and the engine was run for five to 10 minutes. But today's outboards can be flushed using other, in some cases easier methods, some even without starting the engine.
Low Water pick Flushers are Patented design for low water pickup gear-cases. Designed with the largest possible water intake for maximum water capacity the ultimate cooling and flushing. Best way to completely flush your engine.
Salt and brackish water is a corrosive killer on the aluminum which outboards are made of, so flushing every time after saltwater use is a must. Left unchecked inside the cooling passages, saltwater will quickly build up and may cause cooling blockages, leading to overheating and, over time, can corrode an engine from inside out. All outboard manufacturers recommend flushing (according to the procedures outlined in the engine owner's manual) after every use in salt, brackish, dirty, or polluted waters. Operating an engine in sandy, silty, or muddy fresh water also dictates the need for periodic flushing.
