A Mercury Sport Master flusher is a device used to flush outboard motors, specifically, those manufactured by Mercury Marine, with a Sport Master gear case but also fits the Buckshot Racing #77 Nose Cone and Bob's Nose Cone. This will work with the CLE in a pinch.
 
Flushing an outboard motor involves connecting a hose to the motor's flushing port and running fresh water through the engine to remove salt, sand, and other debris that may have accumulated during use in salt water or other harsh conditions.
 
The Sport Master flusher is designed to fit the unique shape and configuration of the Sport Master gear case, ensuring a proper flush and maintenance of the motor. It helps to prolong the life of the outboard motor by preventing corrosion and ensuring proper cooling system function.
 
Flushing an outboard motor after each use in salt and fresh water is a key part of maintenance. It clears the cooling passages of salt residue and scale, which can impede the flow of cooling water through the engine.
 
This can build up and up until the water gallery is completely blocked. You can run your engine on the flush attachment without burning up your impeller as long as you keep the engine at idle. However, you should never rev the engine up while it's on the flush attachment.
