Flush Onboard Adapter

This flush adapter is designed specifically for onboard water systems and shower hoses, using the thinner water lines. It allows fresh water to be routed through the engine cooling system directly from the onboard water supply, making engine flushing possible even when a standard hose connection is not available. Ideal for use on the water or during quick maintenance between rides when not docked.

The adapter provides a secure fit and reliable flow, helping to rinse out salt, sand, and debris to support long-term engine reliability.
