- Allows faster hose attachment and removal during maintenance.
- Uses a UV-resistant ABS housing intended for marine environments.
- Aftermarket replacement; not an original equipment manufacturer component.

- Snap the hose coupler onto the installed male valve until it locks securely.

Troubleshooting & FAQ
How can I confirm fitment for my engine year?
Compare the engine brand, model, horsepower, stroke, model year or serial range, and original flush-port configuration with the information above. The listed horsepower ranges are general application information and do not replace model-specific verification.
Is this an OEM part?
No. This is an aftermarket replacement kit associated with the listed manufacturer part-number references. It is not supplied as an original Mercury, Suzuki, or Yamaha component.
What is the benefit of the quick-connect design?
Once installed on a compatible engine, the male valve remains in place and the hose can be attached or removed using the quick-connect coupler instead of repeatedly removing a threaded flush-port plug.
My engine is not listed. Will it fit?
Do not assume fitment based only on appearance. Confirm the thread size, sealing method, port location, and manufacturer application information before purchasing for an unlisted engine.
The connection is leaking. What should I check?
Stop using the connection and inspect the threads, sealing surface, gasket or O-ring, and quick-connect coupler for dirt, damage, or incorrect seating. Confirm that the valve is tightened securely without overtightening. If the leak continues, discontinue use and consult a qualified marine technician.
How often should I flush my outboard?
Freshwater flushing is commonly recommended after operation in saltwater and may also be appropriate after use in brackish, silty, or contaminated water. Follow the specific flushing instructions in your engine owner's manual.
What shipping and warranty terms apply?
Shipping availability, delivery time, return eligibility, and warranty handling depend on the order and applicable store policies. Review the current checkout and policy information before purchasing.
Safety & Important Information
- Verify the original part, thread configuration, and engine-specific fitment before installation.
- Do not operate the engine or supply water contrary to the engine manufacturer's flushing procedure.
- Inspect the connection for leaks before and during use.
- This is an aftermarket replacement, not an OEM component.
- Professional installation is recommended when the original port is damaged or fitment is uncertain.
