T-H Marine Quick Flush Kit QF-2K for Mercury and Yamaha Outboard Engines, Blue

The T-H Marine Quick Flush Kit QF-2K is a transom-mount engine flushing attachment built to connect a garden hose to a Mercury or Yamaha outboard engine for flushing after use in saltwater or brackish water. Regularly flushing the cooling system helps clear out salt, sand, and debris from the engine's water passages, which supports long-term engine reliability. The kit is molded from durable plastic in a blue finish and is designed for gasoline outboard engines. It mounts to the transom for quick, repeatable connection each time the boat is used, making the flushing routine faster and more consistent than removing hoses or using a flush bag. This kit is intended for boat owners who want a permanent, dedicated flush point rather than a one-time-use adapter. Because it is purpose-built for Mercury and Yamaha outboard applications, it provides a direct fit without modification for those engine families. The compact, lightweight design keeps it out of the way when not in use while remaining ready for the next flush cycle.
