Outboard Motor Flusher – Universal Muff Flusher for Outboard & I/O Sterndrive

Key Features

• Dual Flow & Single Flow Options – Dual-flow models deliver water to both sides of the lower unit simultaneously for thorough, even flushing; single-flow for compact engines
• Marine-Grade Rubber Muffs – Available in oval or rectangular muff shapes; thick, flexible rubber seals tightly against the water intake for a leak-free flush
• High-Quality Steel Bracket – Rigid powder-coated steel frame holds the muffs firmly in position during flushing; no slipping or repositioning needed
• Universal Fit – Compatible with most outboard motors and I/O sterndrives; standard garden hose thread connection
• Standard Hose Connection – Fits any standard garden hose; no adapters required

Problems Solved

• Removes corrosive salt, silt, and mineral deposits that build up inside the cooling system after saltwater use
• Allows engine warm-up, tuning, and maintenance on dry land without launching the boat
• Prevents overheating and premature wear caused by blocked or corroded cooling passages
• Eliminates the need for a flushing port or dedicated flush kit on older engines
