In addition to the corrosion protection devices, the following steps
should be taken to inhibit corrosion:
IMPORTANT: Corrosion damage that results from the improper
application of antifouling paint will not be covered by the limited
warranty.
1 Painting Boat Hull or Boat Transom: Antifouling paint may be
applied to boat hull and boat transom but you must observe the
following precautions:
IMPORTANT: DO NOT paint zinc anodes or MerCathode Sys-
tem reference electrode and anode, as this will render them inef-
fective as galvanic corrosion inhibitors.
IMPORTANT: If antifouling protection is required for boat hull
or boat transom, copper or tin base paints, if not prohibited by
law, can be used. If using copper or tin based antifouling paints,
observe the following:
2 Avoid any electrical interconnection between the MerCruis-
er Product, Anodic Blocks, or MerCathode System and the
paint by allowing a minimum of 1 in. (26 mm) UNPAINTED
area on transom of the boat around these items.
3 Painting Drive Unit or Transom Assembly: Drive unit and tran-
som assembly can be painted with a good quality marine paint
or an antifouling paint that DOES NOT contain copper, tin, or any
other material that could conduct electrical current. Do not paint
drain holes, anodes, MerCathode system, and items specified by
boat manufacturer.
4 Spray power package components on inside of boat every 2-3
weeks with Quicksilver Corrosion Guard to protect finish from
dulling and corrosion. External power package components may
also be sprayed.
5 All lubrication points, especially steering system, shift and
throttle linkages, should be kept well lubricated.
6 Flush cooling system periodically, preferably after each use.
