Description
Rectangular Motor Flush
Molded PVC/Painted Steel
Outboard Rectangular Motor Flush quickly flushes away salt, sand, minerals, and contaminates from your lower unit cooling system, extending the engine’s service life. Easy-to-use molded PVC cups deliver fresh water to flush the cooling system through side intakes on the lower unit. Simple garden hose connection, no tools required. Great for winterizing, tune-ups, and other maintenance that requires running an outboard engine out of the water. Features rectangular cups for use with larger outboards.
