2. Check Conditions: Apply decals in temperatures between 60°F and 80°F (15°C to 27°C) for optimal adhesive performance.
3. Position Decal: Carefully align each decal using the engine's reference points. The peel-and-stick application allows for minor adjustments during initial placement.
4. Apply Firm Pressure: Use a plastic squeegee or application tool to smooth the decal, working from the center outwards to eliminate air bubbles. Pay special attention to edges and corners.

Troubleshooting & FAQ

How do I confirm this fits my engine?
Reference your engine's serial number and model identification plate, typically found on the transom bracket or engine block. Cross-reference this information with the compatibility chart in our listing. For further confirmation, consult the linked Mercury Serial Number Guide.

How long will these decals last and how should I maintain them?
The expected service life is 5 to 8 years under normal marine conditions. To maximize longevity, regularly clean the decals with mild soap and water, rinse with fresh water after salt water exposure, and avoid using pressure washers directly on decal edges.

What do I do if a decal edge starts to lift or I see an air bubble?
For edge lifting, gently apply heat with a hair dryer or heat gun and use firm pressure to reactivate the adhesive. For air bubbles, you can pierce the bubble with a fine needle and smooth the air out towards the hole.
