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 anti-fouling paint will not be covered by the lim-
ited warranty.
1
Painting Boat Hull or Boat Transom: Antifouling paint may be
applied to boat hull and boat transom but you must observe the fol-
lowing precautions:
IMPORTANT: DO NOT paint anodes or MerCathode System ref-
erence electrode and anode, as this will render them ineffective
as galvanic corrosion inhibitors.
IMPORTANT: If anti-fouling 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 anti-fouling
paints, observe the following:
2
Avoid any electrical interconnection between the MerCruiser
Product, Anodic Blocks, or MerCathode System and the paint
by allowing a minimum of 1-1/2 in. (40mm) UNPAINTED area on
transom of the boat around these items.
3
Painting Drive Unit or Transom Assembly: Drive unit and tran-
som assembly should be painted with a good quality marine paint or
an anti-fouling 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.
