Skip the dripping hose and crusty salt rings—swap in Suzuki’s Water-Flush Plug Gasket 17914-93J01 and keep your DF-series outboard sealed tight during every freshwater rinse. This little washer slips between the plastic flush plug and the mid-section port on DF40 through DF350 models, making sure pressure goes through the pump and jackets—not onto your transom.

Why the OEM gasket matters

• Fuel- and glycol-safe EPDM stays flexible from cool spring mornings to 200 °F hot-soak temps.

• 18 mm outside × 12 mm inside diameter fits the threaded flush plug exactly—no trimming or stretching.

• Squared sealing lip distributes torque evenly, so you can snug the plug hand-tight and walk away.

• Matte-black finish resists UV chalking and hides scuffs inside the access cap.

Practical payoff? Faster flush cycles, no salty drips in the splash-well, and zero air leaks that let impellers run dry. Pop the cowl, pull the old flattened washer, seat this gasket, and twist the plug home—two-minute job, whole-season peace of mind. Keep a spare in the glove box; it’s cheaper than a new impeller and a lot easier than chasing an overheating alarm.
