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.
