Simply remove the OEM Mercury flush port plug, unscrew the Mercury OEM plug from the 3/4" female hose outlet, remove the lanyard from the engine hose, thread in your new Seamule Flush Port Quick Connect to the flush port, reinstall the Seamule Flush Port Quick Connect into the engine cowling, give it a 1/4" turn clockwise to lock it in place. 

Helpful Tip: Remove cowling and inspect the flush hose for any kinks in the hose, if there is a kink, replace the Mercury 3/4" female hose outlet with the provided elbow. Orient the elbow inside the cowling to ensure no kinks are in the Mercury flush hose. (To help insert the 90-degree elbow you can lube the barb or use a heat gun on the flush hose.)
