Never Flush Your Outboard Motor in a Wrong Way

Views:72     Author:EARROW     Publish Time: 2018-12-19      Origin:Site

Back in the 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, sometimes easier methods, without even starting the engine.

 

Why Flush?

Salt and brackish water is a corrosive killer of the aluminum from which outboards are made, 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.

How to Flush Outboards Engine with a Flushing Port:

 Flushing happens one of two ways, depending on whether your engine has a flushing port or not. Ports of the this kind are found mostly on newer engines, manufactured in the last ten years or so. The connection points vary, so it's best to check your owner's manual for where it's located on your specific model.

 Once you've established the motor has a port, and you've found it, the rest is easy:

 1.Connect a garden hose to the port.

 2.Turn on the water.

 3.Let the engine flush for five to ten minutes.
