CARE AND MAINTENANCE
7-4
If you operate in salt, polluted, or brackish waters, your boat should
be equipped with a transom mounted zinc anode to prevent damage
to those metal parts coming in contact with the water. The zinc is, by
design, self-sacrificing. It is slowly eroded away by electrolytic action
and requires periodic inspection for deterioration. If the zinc shows
extreme erosion, it must be replaced to continue protection, or dam-
age to other metal parts may result.
Most engines are equipped with one or more zinc anodes which must
also be inspected regularly for deterioration. Some boat models may
be equipped with an electronic cathode system. This system emits a
low current electrical charge into the water close to the metal compo-
nents. This charge cancels the effect of electrolysis.
Never paint or coat zinc anodes or cathodes with any
substance. Once covered, they do not provide protection
from galvanic corrosion. Replace anodes if they have
deteriorated 50% or more.
Salt Water Corrosion
The entire boat should be rinsed with fresh water and washed imme-
diately after use in salt water. If the boat is used primarily in salt water,
wax the hull monthly and apply corrosion inhibitor to all hardware.
See your dealer for products suitable for the marine salt water envi-
ronment. Fresh water internal flushing is recommended when used in
salt, polluted, or brackish waters. Flush the entire engine cooling sys-
tem with fresh water for at least 5 minutes after use in these waters.
See your dealer for appropriate flushing devices.
GENERAL MAINTENANCE
Marine Growth
If accelerated marine growth is a problem in your area, an anti-fouling
bottom paint may be necessary to slow growth and prevent gelcoat
damage. Before selecting a bottom paint, talk with other boaters and
your dealer to determine which product works best in your area. Many
local variables can affect the selection of paint. Be sure to follow the
paint manufacturer’s directions exactly.
Cleaning
Periodic cleaning is the best way to keep your boat looking new.
Regular washing and waxing keep dirt and scum from building up and
deteriorating the finish. Keeping your boat in “show room” condition
means greater personal satisfaction and higher resale value. Special
cleaning products are available from your dealer to remove mildew.
