General Maintenance

Maintaining Power Package Exterior Surfaces
Entire power package should be sprayed at recommended intervals with Quicksilver
Corrosion Guard. Follow instructions on can for proper application.
Entire power package should be cleaned and external surfaces that have become bare
should be repainted with Quicksilver Primer and Spray Paint at recommended intervals.
Steering Head and Remote Control Maintenance
Lubricate steering head and remote control with 2-4-C Marine Lubricant with Teflon. Inspect
steering head and remote control for ease of operation.
Checking Quicksilver MerCathode System
If boat is equipped with a Quicksilver MerCathode System, system should be tested to
ensure that it is providing adequate output to protect underwater metal parts on boat. Test
should be made where boat is moored, using Quicksilver Reference Electrode and Test
Meter. Refer to SECTION 7.
Maintaining Anodic Plate
Each sterndrive unit is equipped with a sacrificial anodic plate to help protect underwater
metal parts from galvanic corrosion. Because of its self-sacrificing nature, anodic plate
MUST BE replaced if eroded 50% or more. Refer to SECTION 7.
Boat Bottom Care
To achieve maximum performance and fuel economy, boat bottom MUST BE kept clean.
Accumulation of marine growth or other foreign matter can greatly reduce boat speed and
increase fuel consumption. To ensure best performance and efficiency, periodically clean
boat bottom in accordance with manufacturer's recommendations.
In some areas, it may be advisable to paint the bottom to help prevent marine growth. Refer
to the following information for special notes about the use of anti-fouling paints.
Anti-fouling Paint
IMPORTANT: Corrosion damage that results from the improper application of anti-
fouling paint will not be covered by the limited warranty.
Painting Boat Hull or Boat Transom: Anti-fouling paint may be applied to boat hull and
boat transom but you must observe the following precautions:
IMPORTANT: DO NOT paint anodes or MerCathode System reference electrode and
anode, as this will render them ineffective as galvanic corrosion inhibitors.
