What Does This Part Do?

The 09280-26006 is a genuine Suzuki Marine nitrile rubber O-ring seal. It is a highly versatile, heavy-duty seal used across two distinct primary maintenance areas on Suzuki 4-stroke outboard motors:

1. Water Pressure (Poppet) Valve Assembly

This O-ring sits directly underneath the 17611-90J00 water pressure valve cover. It prevents salt water from escaping the engine block cooling passages where the poppet valve operates.

• When to replace: Every time you open the cover to clear out sand, debris, or salt crust, or when doing a routine thermostat replacement.

2. Oil Filler Cap Seal

This exact same part number serves as the primary rubber sealing ring for the plastic engine oil filler cap (Part # 11382-93J00 or 11382-99E00) on top of the engine cowling area.

• When to replace: If you notice engine oil weeping or residue pooling around the base of your yellow or black screw-in oil fill cap.
