Installation Guide

For a successful application, ensure the surface is clean, dry, and within the recommended temperature range of 50°F-90°F (10°C-32°C). If applying to a newly painted surface, allow at least 30 days for the paint to cure fully.

1. Thoroughly clean the engine cowling with a degreasing agent to remove any wax, oil, or debris.
2. If necessary, remove old decals using a heat gun on a low setting and a plastic scraper to avoid damaging the surface.
3. Ensure the surface is completely dry and at the proper temperature before application.
4. Carefully position the new decals using alignment guides or reference photos of the original placement.
5. Apply the decal starting from the center and moving outward to prevent and remove air bubbles.
6. Use firm, even pressure with a squeegee or a soft cloth to secure the decal to the surface.
7. Allow the decals to cure for at least 24 hours before exposing the engine to water.

Troubleshooting & FAQ

How do I confirm these decals will fit my specific Yamaha 40HP engine?
First, check the compatibility table on this page. For precise verification, locate your engine's identification plate on the port (left) side of the motor. This plate contains the model code, horsepower, and serial number. You can use our Yamaha Serial Number Guide linked above to identify the manufacturing year from the serial number.

Are these decals identical to the original Yamaha decals?
This is a high-quality aftermarket reproduction set. We produce our decals to exact OEM specifications using the same grade of marine vinyl, UV-resistant inks, and manufacturing processes. While there may be minor, unnoticeable variations in color shades compared to original factory decals, they deliver an authentic appearance at a lower cost.

How should I care for these decals after installation?
Clean the decals using a mild soap and water solution. Crucially, avoid abrasive cleaners or high-pressure washing, as this can damage the vinyl or cause the edges to lift. We recommend inspecting the decals annually for any signs of peeling or damage.

What should I do if I see bubbles under the decal after applying it?
If small air bubbles are present after installation, you can remove them by pricking the bubble with a fine pin and then smoothing the area down with your finger or a soft cloth. Poor adhesion or edge lifting is often due to improper surface preparation or temperature; ensure the surface was clean and within the 50°F-90°F range during application.
