Installation Notes

Clean the surface thoroughly with a suitable solvent to remove any grease, wax, or debris.
Ensure the application surface is completely dry before proceeding.
Carefully peel the decal from its backing paper, avoiding contact with the adhesive.
Position the decal on the desired surface without applying pressure to allow for adjustments.
Once aligned, use a squeegee or credit card to press the decal firmly from the center outwards.
Work out any air bubbles and ensure all edges are securely adhered to the surface.
Allow at least 24 hours for the adhesive to fully cure before exposing the decal to water.

Troubleshooting & FAQ

How do I know if this decal set will fit my sterndrive?

This set is specifically designed for MerCruiser models like the Alpha One Gen I (1983–1990), Alpha One SS (1986–1989), and SSM drives (1982-1995). To guarantee fitment, always check your engine's model and serial number against the compatibility table provided on this page.

Can I apply these decals myself?

Yes, installation is a straightforward process. For professional results, follow the installation steps provided. The key is to ensure the surface is perfectly clean, dry, and that you apply firm, even pressure to remove all air bubbles.

How durable are these decals in a marine environment?

These decals are made from high-quality, marine-grade vinyl. They are designed to resist damage from sun exposure, saltwater, and abrasion, ensuring long-lasting color and adhesion when applied correctly.
