Flushmaster – Flush Port Reroute 3/8" | Quad Outlet | Horizontal | Black Acrylic Plate

The Flushmaster Flush Port Reroute is a professional-grade solution designed to make outboard flushing safer, cleaner, and easier to access. This quad outlet system features a horizontal black acrylic plate with 3/8" barb fittings, allowing you to relocate OEM flush port connections to a centralized panel inside the boat.

This quad-outlet reroute creates a single flushing hub for four-engine boats, reducing clutter and improving access. Instead of reaching over the transom or balancing around brackets, the flush point is moved to a cleaner location where the connection is easier to manage. The horizontal layout is a strong choice for wider mounting surfaces and clean side-to-side hose routing. The black acrylic plate gives the install a clean, custom-rigged look that pairs well with modern transoms and dark accent panels.

How It Works

The Flush Port Reroute moves your engines’ OEM flush ports to a clean, accessible panel inside the boat. Reinforced marine-grade hose is routed from the engine flush connection through the existing rigging tube and secured to the reroute plate, creating a centralized flush point without climbing, stretching, or leaning over the motor.

• Choose the mounting location for the reroute plate.
• Access the flush line inside the engine cowling and integrate reinforced hose using standard rigging practices.
• Guide the hose through the cowling into the rigging tube and run it to the reroute plate.
• Use the included template to prepare the mounting area.
• Secure the hose line to the 3/8" barb fittings and mount the plate.
• When it is time to flush, connect your garden hose to the new flush point for easier dockside maintenance.
