Installation Notes
- Ensure the engine is off and has cooled down before starting.
- Locate the factory flush port on your outboard engine's housing.
- Carefully unscrew and remove the existing OEM flush port plug or cap.
- Clean the threads and the surrounding area to ensure a clean, debris-free surface for a good seal.
- Install the new male nipple valve from the kit, hand-tightening first, then giving it a gentle final turn with a wrench if needed. Do not overtighten.
- Attach the female quick-connect coupler to your standard garden hose.
- To flush, snap the hose coupler onto the newly installed male valve until it clicks securely in place.
- Turn on the water supply and flush the engine according to the manufacturer's specific procedure.
- After flushing, turn off the engine and water supply. Disconnect the hose coupler by pulling back its collar. The male valve remains permanently on the engine.
Troubleshooting & FAQ
How do I know if this kit fits my specific engine year?
This kit is designed for the specified HP ranges across Mercury, Suzuki, and Yamaha. While it fits most models in those ranges, year-specific data is not always available. We highly recommend comparing your existing flush port to the product images and specifications before ordering.
What is the difference between this and the original OEM part?
This kit is an aftermarket upgrade that replaces the standard flush plug with a permanent quick-connect system. It offers the convenience of not needing to screw and unscrew a plug for every flush. It is made from durable, UV-resistant ABS plastic, designed to meet or exceed OEM specifications.
How often should I flush my engine?
It is best practice to flush your outboard engine with fresh water after every use in saltwater, and periodically after use in freshwater, especially in silty or brackish conditions. Refer to your engine’s owner's manual for specific recommendations.
My engine isn't listed, but the part looks the same. Will it fit?
Fitment is only guaranteed for the models listed. While it may fit other engines that use a similar flush port, we cannot confirm compatibility. Purchasing for an unlisted model is at your own risk.
The connection is leaking. What should I do?
First, ensure the male valve is securely tightened onto the engine block and that the threads are clean. Check if an O-ring or gasket was required and is properly seated. If leaking from the quick-connect coupling, ensure it's fully snapped on and inspect the coupler's internal seal for debris or damage.
