Installation Notes

Thoroughly clean the cowling surface with a mild detergent and water, then dry completely. Remove any wax, grease, or old adhesive residue.
Carefully position the new decal, using masking tape to create a hinge or reference points for accurate alignment.
Begin applying the decal from the center and work your way outward, using a squeegee or credit card to smooth it down.
Press firmly across the entire decal to ensure strong adhesion and remove any air bubbles.
Allow the adhesive to cure for at least 24 hours before exposing the motor to water or extreme conditions.

Troubleshooting & FAQ

Will these decals fit my specific Yamaha F90 model year?

These decals are designed for a wide range of Yamaha 90HP 4-Stroke models. As exact year ranges are not specified, we strongly recommend visually comparing this kit's layout with your motor's existing graphics before ordering to ensure a perfect match.

How do these aftermarket decals compare to the original OEM graphics?

Our decals are engineered to meet or exceed OEM standards. They are made from high-quality, durable vinyl with a protective laminate designed to match OEM color and specifications, ensuring resistance to UV rays, salt water, and fuel.

What is the best way to remove old decals before applying this new kit?

Gently heat the old decals with a heat gun or hairdryer on a low setting to soften the adhesive. Use a plastic scraper or your fingernail to carefully peel them off. Clean any remaining residue with an isopropyl alcohol or an adhesive remover before applying the new set.

Can I apply wax over the new decals?

Yes. After the decal adhesive has fully cured (we recommend waiting at least 48 hours), you can apply a quality marine-grade wax over the decals. This adds an extra layer of protection against the elements and enhances gloss.

What if I see bubbles or wrinkles during installation?

If small bubbles appear, you can often push them to the edge with a squeegee. For a persistent bubble, prick it with a fine needle and press the air out. Wrinkles can sometimes be fixed by gently lifting the decal and reapplying with even pressure.
