Product Details

This Water Flush Plug – Fits Suzuki 4-Stroke 8-350HP (Replaces 17913-93J00) is designed for Suzuki 4-Stroke outboard engines from 8HP to 350HP (models 2008 and newer).

What’s in the Box

  • 1 x Water Flush Plug (17913-93J00)

Note: The companion gasket (part number 17914-93J00) may be sold separately depending on the retailer. Some sellers package them together. Please check what is included at the time of purchase.

Installation Notes

  1. Ensure the engine is off and tilted to the full 'up' position (trailer position).
  2. Locate the flush port on the side of the engine cowling. It is typically covered by this threaded plug.
  3. Unscrew the existing flush plug by hand. Keep it in a safe place if you plan to reuse it.
  4. Inspect the threads on the engine port for any debris or damage. Clean if necessary.
  5. Check that your new plug has its gasket correctly seated (if it comes with one).
  6. Screw the new water flush plug into the port until it is hand-tight. Do not overtighten, as this can damage the plug or threads.

Troubleshooting & FAQ

How do I use this plug to flush my engine?

To flush your engine, you unscrew this plug and attach a hose adapter (sold separately) connected to a standard garden hose. Turn on the fresh water and let it run through the cooling system for 5-10 minutes with the engine OFF. Once done, remove the adapter and screw this plug back in place.

Is the gasket (17914-93J00) included?

This listing is for the plug only. Some retailers bundle the plug and gasket together, while others sell them separately. Always verify the contents of your purchase. Using a new gasket or ensuring the old one is in good condition is recommended for a proper seal.

What happens if this plug is missing or leaky?

A missing or damaged flush plug can allow water to enter the engine cowling while underway, potentially exposing sensitive electronics to saltwater and causing corrosion. It also prevents you from properly flushing the engine. A leak during flushing reduces water pressure, making the flush less effective.

How often should I flush my outboard engine?

It is best practice to flush your engine with fresh water after every use in saltwater. For freshwater use, flushing is still recommended periodically to clear out any silt, sand, or algae from the cooling passages.

Will this fit my Johnson/Evinrude engine?

While some sources suggest cross-compatibility with certain Johnson/Evinrude models, we cannot guarantee fitment without specific model and year information. Please verify the part number for your specific engine before ordering.

This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
