Read this quick overview on how to protect you engine
from corrosion!What causes corrosion? Seawater is a good conductor
and freshwater a bad conductor, so corrosion is worse in
seawater. Generally, corrosion rates increase in proportion to the
amount of oxygen in the water. However, cracks and crevices,
which are areas starved of oxygen, become anodic and corrode
also. Higher temperature increases corrosion rates - doubling for
every 30 degrees C (55 degrees F). There are various
types of microorganisms that can contribute to corrosion, either by
removing protection or causing a corrosive environment.Why do I need
anodes? You need anodes on your engine because when
two different metals are in contact, electrons will flow from
the more negatively charged metal (anode) to the more positive
metal (cathode). If you want to protect both types of
metal from corrosion, you must add a third metal such
as zinc, although magnesium and aluminum are also used. This
active metal becomes the anode for both metals. The
zinc or aluminum sacrifices itself to protect the other two
metals, hence the term "sacrificial anode".Do's and Don'tsDO change your
anode when they are 50 percent corroded DO make sure
they make good electrical contact - remove paint and clean
the mounting surface.DO protect trim tabs individually (do not bond).
Although they are usually made from stainless steel they can
still corrode and need sacrificial anodes.DO be sure to use
new fasteners on sterndrives - even stainless bolts fail as
a result of corrosion.DO keep a sterndrive immersed in the
water so that the anodes can work. DON'T use zinc
anodes on aluminum outdrivesDON'T paint anodes. They will not work
to their full potential!DON'T mix anode types - aluminum anodes
will try to protect zinc.DON'T use magnesium anodes on outdrives
in salt or brackish water as it will "overprotect" the
aluminum. Canada Metal Tear Drop Zinc
