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. Algae,
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 den-
sity and superior adhesion properties provides an
exceptionally effective barrier to osmotic blister-
ing. Osmosis is caused by a chemical reaction
between water and substances in the hull laminate
below the waterline.  If water breaches the ex-
terior gelcoat and barrier layer, it can react with
the chemical components in the laminate creat-
ing acidic substances.  These substances create
pressure 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.

CAUTION

BARRIER COATINGS AND BOTTOM PAINT SHOULD BE APPLIED

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.

CAUTION

DO NOT ALLOW THE HULL ANTIFOULING PAINT TO CONTACT

THE OUTDRIVE OR OUTBOARD MOTOR. MOST ANTIFOULING

PAINTS DESIGNED FOR HULL BOTTOMS CONTAIN COPPER

AND CAN CAUSE SEVERE GALVANIC CORROSION DAMAGE TO
THE DRIVE UNIT. USE ONLY ANTIFOULING PAINT DESIGNED

FOR OUTDRIVES AND OUTBOARD MOTORS. ALWAYS LEAVE A

ONE INCH BARRIER BETWEEN THE HULL BOTTOM PAINT AND

OUTDRIVE OR OUTBOARD MOTOR.

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 fresh water cooling system, catalytic
converter raw water exhaust manifold and the
outdrive. Outboard motors have anodes on the
engine bracket and drive unit. 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.
