What’s in the Box

  • 1 x Yamaha 225 HP Outboard Motor Top Cowl Cove Decal Sticker Kit (Interchange for 24DC915Y225 / 24DC918Y225)

Installation Notes

  1. Prepare the Surface: Thoroughly clean the engine cowling with a degreaser to remove all wax, oil, and debris. The surface must be perfectly clean for proper adhesion.
  2. Create Application Fluid: Mix a few drops of mild dish soap with water in a spray bottle.
  3. Position the Decal: Lightly spray the cowling surface and the adhesive side of the decal with the soap solution. This "wet application" allows you to slide the decal into its final position without it sticking immediately.
  4. Squeegee Firmly: Once positioned, use a soft squeegee to press the decal onto the surface. Work from the center outwards to push all water and air bubbles from underneath.
  5. Allow to Cure: Let the decal dry completely for at least 24 hours before exposing it to heavy water spray or harsh conditions. Curing time may vary with temperature and humidity.

Troubleshooting & FAQ

How do I ensure these decals fit my Yamaha engine?

This kit is designed for Yamaha F225 4-Stroke V6 3.4L outboard models. The most reliable method is to visually compare the decal shapes in our product photos with your current engine cowling. If your cowling design differs, this kit will not fit.

How long will the color last in the sun?

These decals are printed on high-quality marine-grade vinyl with a clear UV-protective laminate. They are rated to resist fading for approximately 8 to 10 years with typical sun exposure.

What is the difference between these and original Yamaha decals?

Ours are aftermarket reproductions, not OEM parts. They are designed to match the original factory decals in size, color, and durability, offering a high-quality alternative at a better value.

Can I apply these decals dry?

While dry application is possible for experienced installers, we strongly recommend a wet application using a soap/water solution. This method is forgiving for first-time installers, as it allows you to reposition the decal for perfect alignment before it permanently adheres.
