Installation Notes

1. Verify that the replacement part matches the original fitting in thread size, thread form, length, material, and application location.
2. Confirm the engine model and complete serial-number range against the applicable parts catalog before installation.
3. Remove the original fitting only after the engine and related systems have cooled and been depressurized.
4. Clean the threaded opening and remove old sealant, debris, or corrosion without damaging the mating threads.
5. Apply a sealant approved for the specific engine system and service fluid, following the engine manufacturer's instructions.
6. Start the fitting by hand and keep it properly aligned to prevent cross-threading.
7. Tighten only to the manufacturer's service-manual specification. Do not overtighten the brass fitting.
8. After installation, inspect the area for leakage during the appropriate system test or engine run-up.

Troubleshooting & FAQ

Is this a complete kit?

No. This listing is for one brass pipe plug fitting. Sealant, tape, washers, and other installation materials are not included unless specifically stated by the seller.

What does Mercury 22-36382 refer to?

Mercury 22-36382 is the OEM reference associated with this replacement fitting. The catalog description identifies the part as a brass fitting with a .250-18 thread specification and a 0.62-inch length.

Will this fit every marine engine with a 1/4-inch threaded port?

No. A matching nominal thread does not by itself confirm complete compatibility. Verify the thread form, length, material, application location, engine model, and serial-number range before installation.

Can the fitting be reused?

Reuse is not recommended without careful inspection. Replace the fitting if the threads are damaged, deformed, corroded, pitted, or previously over-tightened. Use fresh approved sealant during reinstallation.

What torque specification should be used?

Use the torque value specified in the applicable engine service manual. No universal torque value should be assumed for every engine, material, or threaded application.

How can I check fitment before ordering?

Compare the original part and application diagram, then verify the complete engine model and serial number. Pay particular attention to the listed .250-18 specification and 0.62-inch length.

Is this an OEM part?

This listing is for an aftermarket replacement associated with Mercury OEM reference 22-36382. It is not represented as a genuine Mercury-branded component.

Safety & Important Information

• Do not rely on horsepower or model family alone to confirm fitment; serial-number conditions and application location must also match.
• Do not install a fitting with damaged, contaminated, or mismatched threads.
• Use only a sealant compatible with the engine system and service fluid.
• Follow the engine manufacturer's service instructions and leak-test the repaired system before normal operation.
