Mercury 200 Verado FourStroke Operation And Maintenance Manual page 77

Routine cleaning of the remote control external surfaces is recommended to
prevent a buildup of salt and other environmental debris. Use a cloth towel
which has a sufficient amount of fresh water to dissolve and remove salt or
mineral deposits.
When water marks cannot be removed with a damp cloth, mix a 50/50 solution
of warm water and isopropyl alcohol to clean the remote control. Do not use
acetone, mineral spirits, turpentine type solvents, or ammonia based cleaning
products. The use of strong solvents or detergents may damage the coating,
the plastics, or the rubber components on the remote control.
CLEANING CARE FOR TOP AND BOTTOM COWLS
IMPORTANT: Dry wiping (wiping the plastic surface when it is dry) will result in
minor surface scratches. Always wet the surface before cleaning. Do not use
detergents containing hydrochloric acid. Follow the cleaning and waxing
procedure.
Cleaning and Waxing Procedure
1. Before washing, rinse the cowls with clean water to remove dirt and dust
that may scratch the surface.
2. Wash the cowls with clean water and a mild nonabrasive soap. Use a soft
clean cloth when washing.
3. Dry thoroughly with a soft clean cloth.
4. Wax the surface using a nonabrasive automotive polish (polish designed
for clear coat finishes). Remove the applied wax by hand using a clean
soft cloth.
5. To remove minor scratches, use Mercury Marine Cowl Finishing
Compound (92‑859026K 1).
CLEANING CARE FOR THE POWERHEAD (SALTWATER USE)
IMPORTANT: If the outboard is operated in saltwater, remove the top cowl.
Inspect the powerhead and powerhead components for salt build‑up. Wash off
any salt build‑up from the powerhead and powerhead components with fresh
water. Keep water spray out of the air filter/intake and alternator. After washing,
allow the powerhead and components to dry. Apply Quicksilver or Mercury
Precision Lubricants Corrosion Guard spray on the external metal surfaces of
the powerhead and powerhead components. Do not allow the Corrosion Guard
spray to come in contact with the alternator drive belt, belt pulleys, or the
outboard motor mounts. The alternator drive belt could slip and be damaged if
it becomes coated with any lubricant or Corrosion Guard spray.
