FlushMaster 4-Port Automated Flushing System — Two 12 ft Hose Kits — SMFM4012
The FlushMaster 4-Port Automated Flushing System takes the effort out of post-use engine maintenance. Designed for multi-engine setups, it automatically flushes up to four outboard engines sequentially — with a pre-programmed 15-minute flush per port and automatic shutoff when complete. Battery-operated and fully portable, it requires no shore power and is built from marine-grade materials with an IP67 waterproof rating. This kit includes two 12-foot EPDM hose kits for extended-reach installations.

Parts Desk Insights
Best use case: The FlushMaster 4-Port is the right solution for twin, triple, or quad outboard setups where flushing multiple engines after every saltwater outing is time-consuming and easy to skip. It’s particularly well-suited for centre console fishing boats, offshore sportfishers, and commercial vessels with multiple outboards. The 12 ft hose kits make it ideal for wider transoms or engine configurations where the engines are spread further apart. Set it up once at the dock or on the trailer, connect the flush port adapters, and walk away — the system handles the rest. Note that flush port quick connect adapters (sold separately) are required for each engine and are brand-specific — order the correct adapter for each engine brand in your setup.
