Troubleshooting & FAQ

How do I confirm this kit fits my engine?
First, check the compatibility table on this page. Your engine should be a Mercury 20HP 4-Stroke model from the years 1999-2006. For definitive confirmation, locate the identification plate on your engine's transom bracket or block and use our Mercury Serial Number Guide to cross-reference the number.

What is the best way to remove old decals?
Gently heat the old decals with a heat gun or hair dryer to soften the adhesive. Use a plastic scraper or razor blade to carefully peel them off. Any remaining adhesive residue can be removed with an adhesive remover or isopropyl alcohol.

How can I prevent the new decals from peeling or lifting?
Proper surface preparation is key. The surface must be perfectly clean and dry before application. Applying firm, even pressure with a squeegee, especially on the edges, will ensure a strong bond. Allow 24 hours for the adhesive to fully cure before exposing it to water.
