Technical Specifications

Package Contents

• 1 x Outboard Flush Plug (Replaces 17913-99E12)
• Note: The O-ring gasket (09280-13005) is not included with this plug and must be purchased separately.

Installation Guide

1. Locate the flush port on your Suzuki outboard engine. It is typically covered by a black plastic cap.
2. Unscrew the existing cap or plug by turning it counter-clockwise.
3. Inspect the port and ensure the O-ring or gasket from the old plug is removed and the area is clean.
4. If you have a new O-ring, place it onto the new flush plug.
5. Screw the new flush plug into the port by hand until it is snug. Do not overtighten.
6. Attach a standard garden hose to the threaded connection on the plug.
7. Turn on the water supply to a moderate pressure. Run the engine at idle for 5-10 minutes to flush the cooling system with fresh water.
8. After flushing, turn off the water and detach the hose.
9. Unscrew the flush plug and reinstall the original engine port cap.

Troubleshooting & FAQ

Q: How do I confirm this fits my engine?
A: Check your engine model and year against the "Compatible Engine Models" table. This part is specifically for older, non-A model Suzuki engines (e.g., DF90, DF115, DF140). If you have a newer "A" or "B" series Suzuki outboard, this part will not fit.

Q: Does this flush plug come with the O-ring gasket?
A: No, the O-ring gasket (part number 09280-13005) is not included. It is recommended to purchase one separately or reuse your existing one if it is in good condition to ensure a watertight seal.

Q: Why is it important to flush an outboard engine?
A: Flushing removes salt, sand, and other corrosive debris from the engine's internal cooling passages. Regular flushing after use in saltwater is critical for preventing corrosion, blockages, and overheating, which extends the life of your outboard.
