The 12 oz can is formulated to meet Mercury Marine OEM specifications for performance guidance on outboards and sterndrives.

TotalBoat Outdrive AF Aerosol for Underwater Metals
Best for: Boaters seeking corrosion protection on underwater metal surfaces such as propellers, outdrives, and trim tabs. The formula includes zinc-based components to inhibit corrosion and is designed for fast-drying, multiple coat protection across the season. It is especially suitable for multi-metal environments typical of lower units.
Caution: Apply in several light coats rather than heavy layers to ensure even coverage and prevent runs. Recoat after recommended drying intervals for best protection.
Johnson/Evinrude/OMC New OEM White Acrylic Spray Paint
Best for: White engine paints on Johnson/Evinrude/OMC equipment from 1981–1991 with a requirement for OEM-style color and durability. The 12 oz spray is designed for older models, helping to restore a factory-like finish on both outboard and stern drive components.
Limitation: Fitment may vary across Johnson and OMC models; verify compatibility with your specific engine before purchase.
MERCURY 802878020 Verado Silver Enamel Spray Paint
Best for: Silver-coated gearcases, lower units, and Mariner outboards with silver cowls. This enamel spray is produced by Mercury Marine to align with their OEM specifications for a seamless silver finish that matches factory looks.

Moeller 025479 Ep Omc Marine Paint, Charcoal Metallic
Best for: Broad engine coverage including outboards, inboards, stern drives, and lower units with a charcoal metallic finish. The acrylic lacquer formulation provides extended staying power for marine environments and uses a large button spray to coat larger areas efficiently.

Moeller 6961 Johnson/Evinrude White (OEM #173744)
Best for: Outboard and inboard engines requiring a white OEM match with strong solvent resistance. This paint is designed for extended staying power in marine service, including lower unit components that experience exposure to fuel and heat.
Limitation: White finishes can show imperfections more readily; careful prep and even coats yield the best results.
Buying Guide
What finish should I choose for lower units?
Gloss finishes provide a high-gloss look and can be easier to wipe clean, while satin or matte finishes hide minor imperfections. For durability in saltwater, enamel or acrylic lacquers with a marine-grade formulation tend to hold up best against exposure and abrasion.
How important is OEM color matching?
For a seamless appearance, choose colors that match your engine’s OEM shade. This is especially true for modern Mercury/Mariner and MerCruiser systems, where color consistency can preserve resale value and aesthetics.
What prep steps improve paint longevity?
- Thoroughly clean and dry the surface.
- Lightly scuff with fine-grit sandpaper to improve adhesion.
- Use a compatible primer if recommended by the manufacturer.
- Apply multiple light coats rather than a single heavy coat.
How many coats should I apply?
Typically two to three coats provide adequate coverage and durability. Follow the product’s drying times between coats to prevent runs and ensure a smooth finish.
What are common limitations to expect?
- Some colors may require specific primers or sealants to prevent peeling in harsh marine environments.
- High-shine enamel can show surface imperfections if the prep work isn’t thorough.
Environmental and safety considerations
Paints should be applied in well-ventilated spaces, away from open flames. Wear protective gear and follow local regulations for disposal of aerosol cans and rags used during painting.
Maintenance tips after painting
- Rinse with fresh water after saltwater use to minimize corrosion risk.
- Avoid abrasive cleaners that could dull the finish; use mild, marine-safe cleaners.
- Inspect the painted surfaces regularly and touch up any chips to prevent rust.
Frequently asked questions
- Q: Can I use any spray paint on a lower unit?
A: Use paints designed for marine use and for lower units to ensure durability and corrosion resistance. - Q: Do I need a clear coat?
A: A clear coat can add extra protection and UV resistance for some finishes; check product guidelines. - Q: How long before water exposure after painting?
A: Allow full curing per product instructions; touching/watering too soon can compromise adhesion. - Q: Will these paints affect engine performance?
A: When applied correctly to the exterior surfaces, normal coatings do not affect engine performance. Follow manufacturer instructions. - Q: How do I choose between primer and no-primer options?
A: Primers improve adhesion and longevity on bare metal or repaired areas; follow the specific product’s guidance. - Q: Are these paints color-matching to factory finishes?
A: Some options are OEM-matched (like Mercury and Moeller variants); verify color with your engine model and year.
