ROUTINE MAINTENANCE

13.1 Exterior Hull and Deck

Hull Cleaning Below The Water Line
When the boat is removed from the water, clean
the outer bottom surface immediately.
grass, dirt and other marine growth is easier to
remove while the hull is still wet. Use a pres-
sure cleaner or a hard bristle brush to clean the
surface.
Marine Growth, Bottom Paint and
Osmosis Blistering
If the boat is to be left in saltwater for extended
periods, the hull must be protected from marine
growth by antifouling paint. Because of variations
in water temperature, marine growth, and pollu-
tion in different regions, a qualified boat yard in
your area should be consulted when deciding what
bottom paint system to apply to your hull. This
is extremely important as pollution and marine
growth can damage fiberglass hulls.
Your Monterey hull is manufactured using state-of-
the-art materials and processes. A layer of super
tough, Ashland "AME" Resin with high density and
superior adhesion properties provides an excep-
tionally effective barrier to osmotic blistering.
Osmosis is caused by a chemical reaction between
water and substances in the hull laminate below
the waterline. If water breaches the exterior
gelcoat and barrier layer, it can react with the
chemical components in the laminate creating
acidic substances. These substances create pres-
sure behind the gelcoat which causes blisters.
CAUTION
SANDBLASTING THE HULL BOTTOM WILL DAMAGE THE
FIBERGLASS. USE A FIBERGLASS WAX REMOVER AND SAND
TO SCUFF THE GELCOAT SURFACE. THE INSTRUCTIONS
AND RECOMMENDATIONS OF THE BARRIER COATING AND
ANTIFOULING PAINT MANUFACTURERS SHOULD BE FOLLOWED
EXACTLY.
BARRIER COATINGS AND BOTTOM PAINT SHOULD BE APPLIED
Algae,
ONLY BY QUALIFIED MARINE PROFESSIONALS IN A BOAT YARD
OR DEALERSHIP THAT SPECIALIZES IN THEIR APPLICATION.
USE ONLY STANDARD, HIGH QUALITY ANTIFOULING PAINTS
AND BARRIER COATINGS FROM NAME BRAND MANUFACTURES
SUCH AS INTERLUX AND PETTIT.
DO NOT ALLOW THE HULL ANTIFOULING PAINT TO CONTACT
THE OUTDRIVE. MOST ANTIFOULING PAINTS DESIGNED FOR
HULL BOTTOMS CONTAIN COPPER AND CAN CAUSE SEVERE
GALVANIC CORROSION DAMAGE TO THE OUTDRIVE UNIT. USE
ONLY ANTIFOULING PAINT DESIGNED FOR OUTDRIVES AND
OUTBOARD MOTORS. ALWAYS LEAVE A ONE INCH BARRIER
BETWEEN THE HULL BOTTOM PAINT AND OUTDRIVE.
Most bottom paints require some maintenance.
Proper maintenance is especially important when
the boat is in saltwater and not used for extended
periods or after dry storage. If the hull bottom
has been painted with antifouling paint, contact
your dealer for the recommended maintenance
procedures.
Sacrificial Anodes
Sacrificial anodes are installed on the inboard
engine's freshwater cooling system, catalytic
converter raw water exhaust manifold and the
outdrive. Additional anodes are installed on the
trim tab planes.
The anodes are less noble than copper based
alloys, aluminum, cast iron and stainless steel.
They will deteriorate first, protecting the more
noble engine and underwater hardware against
galvanic corrosion. Anodes should be checked
monthly and changed when they are 75% of
their original size. Additionally, anodes that are
subjected to frequent wetting and drying require
periodic scraping with sandpaper to remove scale
and oxidation to maintain their effectiveness.
