FlushMaster Flush Port Quick Connect — Mercury Outboard — SMFMQCM
Flush your Mercury outboard faster and cleaner with the FlushMaster Flush Port Quick Connect. This marine-grade adapter connects directly to your engine’s flush port, delivering a full freshwater flush without ear muffs, a water bucket, or running the engine in a tank. Designed specifically for Mercury outboard flush port fittings, it makes post-use maintenance quicker and more consistent — so flushing actually gets done after every outing.
Key Features
- Connects directly to the Mercury outboard flush port — no ear muffs required
- Quick-connect design for fast, tool-free attachment and removal
- Marine-grade construction for long-term durability
- Delivers a thorough freshwater flush to remove salt, silt, and sand from cooling passages
- Compact and lightweight — easy to store aboard or in a gear bag
Compatibility
Designed for Mercury outboard motors equipped with a flush port. Verify flush port fitment with your specific Mercury engine model and year before ordering — flush port configurations vary across Mercury outboard families.
Parts Desk Insights
Best use case: The FlushMaster Quick Connect is the right tool for Mercury outboard owners who want a faster, cleaner flushing routine than traditional ear muffs allow. Particularly useful when flushing at a dock or on a trailer without easy access to position ear muffs, or when the engine is mounted on a bracket where ear muffs are awkward to fit. Saltwater boaters should flush after every outing — this adapter removes the friction from that habit. Mercury flush port fittings differ from Yamaha and Suzuki — confirm this is the correct fitment for your engine before ordering. For Yamaha fitment see SMFMQCY; for Suzuki see SMFMQCS. If you’re stocking for a shop or dealership, the 6-pack counter display (SMFMQCMCD) is also available.
