Different Methods Used to Flush an Outboard Engine

Salt, sediment, and seaweed may enter your sport boat's outboard motor while you are cruising through the ocean at a fast pace. Even if your boat is going to be anchored while you are fishing or using the watercraft as the layout for an outdoor luncheon, salty water that contains particles will enter the motor's casing at some point. Because salt and ocean materials can clog the motor and cause it to overheat or stop running, flushing the engine is necessary and should be performed after each ocean water adventure.

Use a Muff or a Flushing Bag

A muff or a flushing bag are two materials that can be secured to a garden hose and will direct water into the water intake valve. A muff is a marine accessory that contains flaps that will cover the front of the motor casing, that contains an opening. A hose will need to be secured to the center of the muff, resulting in a direct path for the water to flow through. Once the muff is attached, the motor should be turned on. This will prevent overheating. During the flushing process, the components of the motor will spin and any foreign materials will be released. A flushing bag is similar to a muff, but is slightly wider and longer in size. A bag can be attached to an outboard casing and will cover the front opening and the sides of the casing. Just like with a muff, a flushing bag will need to be secured to a garden hose and a watercraft motor will need to be turned on during the flushing process. Both of these flushing methods should be performed on dry land. 

Secure a Hose to a Built-In Attachment

Modern boats that were manufactured in the last decade often have a built-in attachment, which can be used for a boat motor engine flush. With this type of attachment, the motor does not need to be turned on. Look at your owner's manual and inspect your watercraft, to determine the location of the attachment.

If you are fortunate enough to have access to an attachment, secure a garden hose directly to the attachment. Turn on the hose and let the water run for several minutes. Only perform this flushing task whenever you are on dry land. Flushing will prolong the life of your outboard motor and prevent you from needing to scrape residue from internal motor components.
