Installation Notes

Ensure the engine is off and cool. Disconnect the battery.
Clean the area around the old spark plug to prevent debris from entering the cylinder.

Use a spark plug socket to carefully unscrew and remove the old plug.
Verify the gap of the new spark plug is set to 0.9mm (0.035").
Thread the new plug in by hand to prevent cross-threading, ensuring it seats properly.
Tighten the spark plug with a torque wrench to the manufacturer's specification (10.8-14.5 lb-ft for aluminum, 10.8-18 lb-ft for cast iron). Do not over-tighten.

Troubleshooting & FAQ

How do I confirm this fits my engine?

This plug fits specific Yamaha and Suzuki F60/T60 4-Stroke models from 2002–2004. The best way to ensure a match is to compare the part number (DPR5EA-9 or 2887) to the one listed in your engine's service manual or printed on your existing plugs.

What is the correct gap for this plug?

The gap is pre-set at the factory to 0.9mm (0.035"). While they are generally ready to install, it is best practice to double-check the gap with a feeler gauge before installation.

What are the signs of a bad spark plug?

Common symptoms include difficulty starting the engine (hard starts), rough idling, engine misfires (especially under load), reduced acceleration, poor fuel economy, and a "check engine" light.

How often should I change my marine spark plugs?

For most outboard engines, it is recommended to inspect spark plugs annually and replace them every 100-200 hours of operation or as directed by your manufacturer's maintenance schedule. Frequent use in harsh saltwater environments may require more frequent changes.
