Flush Port Quick Connect for Mercury Outboards
The Flush Port Quick Connect for Mercury outboards makes flushing your Mercury outboards easier, faster, and more securely. Designed to replace factory flush ports, this kit installs in minutes and gives you a permanent, leak-free connection built to withstand the toughest marine environments.
Crafted from durable, corrosion-resistant materials, including 316 stainless steel and high-grade polymers, the Flush Port Quick Connect is built for life around saltwater. With the included 90-degree elbow fitting, you’ll avoid hose kinks and ensure maximum water flow for a more complete, effective flush every time.
Whether you're flushing with your Flushmaster system or a standard water hose, this upgrade means no more stripped threads, no more frustration, and no more excuses — just a faster, easier way to protect your engine and extend its life.
