Installation Notes

1. Disconnect spark plug leads and ensure the engine is cool before beginning work.
2. Locate the tell-tale nipple on the lower motor cover assembly.
3. Gently remove the old nipple by pulling or twisting counterclockwise if threaded; avoid using excessive force to prevent housing damage.
4. Clean the mounting bore to remove old sealant, corrosion, or debris.
5. Apply a small amount of marine-grade sealant if recommended by your engine's service manual.
6. Press or thread the new nipple into place, ensuring a firm, even seating.
7. Run the engine briefly and observe the tell-tale stream to confirm proper water flow and sealing.

Troubleshooting & FAQ

How do I know if my tell-tale nipple needs replacement?

Signs include no water stream during engine operation, weak or intermittent flow, visible cracks, or the nipple breaking off. Always inspect the cooling system if overheating occurs.

Is this nipple compatible with all Johnson and Evinrude engines?

No—compatibility is model- and year-specific. Cross-reference your engine model and year with the compatibility table above to confirm fitment.

Will this fit engines not listed in the compatibility table?

Only install this part on engines confirmed in the table or matching OEM part number 321885 / 0321885. Installing on unlisted models may result in improper fit or cooling system failure.

Can I reuse the old nipple if it still looks intact?

It is not recommended. Rubber and plastic components harden and lose elasticity over time, leading to leaks or breakage under pressure.

Do I need sealant when installing this nipple?

Consult your engine's service manual. Some installations require marine-grade sealant around the base; others rely on press-fit alone.

What should I do if the tell-tale stream is weak after installation?

Check for blockages in the cooling water passages, verify proper nipple seating, and inspect the water pump impeller for wear or damage.
