Troubleshooting & FAQ
How do I know if this decal set will fit my sterndrive?
This set is specifically for Mercury MerCruiser Alpha One (Gen II) models from 1998 and newer. Your sterndrive's serial number must be 0L100040 or higher. Please verify this information before purchasing.
Are these decals identical in color and design to the original OEM ones?
These are high-quality aftermarket decals designed to match OEM specifications. However, due to variations in manufacturing lots and aging of original decals, minor differences in color or finish may exist. They are built to restore the original aesthetic of the Alpha One Gen II drive.
How should I prepare the surface before applying the new decals?
Proper surface preparation is critical. You should remove the old decals completely, then clean the area with a solvent like isopropyl alcohol or a dedicated adhesive remover to get rid of any residue. The surface must be perfectly clean and dry for the new decals to adhere properly.
What is the best way to remove old, cracked decals?
Gently heating the old decals with a heat gun or hairdryer on a low setting can soften the vinyl and adhesive, making them easier to peel off. Use a plastic scraper or razor blade carefully to avoid scratching the surface. Any remaining adhesive can be cleaned with a suitable solvent.
Is it necessary to replace faded or peeling decals?
While primarily cosmetic, replacing worn-out decals restores the clean, factory appearance of your equipment, which can be important for resale value. It also ensures the drive is correctly identified as an Alpha One Gen II model.
What is included in the decal set?
The package contains a complete set of decals for one MerCruiser Alpha One (Gen II) sterndrive as pictured, including the main "Alpha One" side decals and any other relevant identification marks for this model series.
