Remove any mold-release wax that may be present
using fiberglass surface prep solvent and a scrub
pad. Scrub only a few square feet at a time. Flush
with fresh water. If the water beads up or separates,
continue scrubbing the surface. When the water
sheets off, the wax contaminate has been removed.
After the dewaxing is complete, application of a
primer coat is recommended. Pay close attention to
scratches, nicks and dings in the surface. If necessary,
fill any repair areas with a watertite-epoxy filler. After
filler is cured, sand with 80 grit paper until smooth.
Remove the sanding residue using a fiberglass
solvent wash. Paint can be applied after sanding and
cleaning is complete. Follow the paint manufacturer’s
recommendations for application.
Bottom Painting a Pre-Painted Hull
If the hull bottom is already painted, test the paint’s
adhesion to the painted surface. If the paints are
incompatible, the new paint will not adhere to the hull
bottom or the paint will lift the old paint. Never apply
paint without first preparing the old painted surface.
Follow the paint manufacturer’s recommendations.
Thin layers are better than one thick layer.
If this vessel will spend most of its time in the water,
painting the bottom of this vessel’s hull is a good
way to slow the formation of hull blisters and to keep
bottom growth (fouling) under control. Conversely, if
you will be trailering the boat to and from the water,
you might want to forgo the painting.
The following is an abbreviated section on painting
the hull bottom. Your Boston Whaler dealer should
have information on properly painting this vessel’s
hull or recommendations on businesses that
specialize in this area.
Bare Hull Painting
Proper preparation is the key to successful hull
painting. Begin by scrubbing the surface thoroughly
with a stiff brush using an all-purpose marine soap
and water to remove loose dirt and contamination.
Flush with fresh water to remove all soap residue.
The gelcoat must be dewaxed of mold-release wax
before sanding can begin, otherwise wax will be
deposited in the scratches and reduce the adhesion
properties of the paint.
Bottom Painting
There are risks and dangers inherent with the
use of paints and solvents. Dispose properly
of all rags, rollers, and trays used for painting.
Follow all the precautions and regulations listed
by the manufacturer before and after painting
this vessel’s hull.

DANGER
!
WARNING
Proper ventilation and capture of the dust
created by sanding is essential. The dust
created by sanding is toxic and should not be
inhaled. A proper fitting respirator must be
used. Do not use a paper filter mask.
NOTICE
If blisters are present in the hull, they need to
be properly cleaned and dried out before any
barrier protection can be applied.
!
WARNING
Bottom paint is designed to resist algae growth
which means it has chemicals embedded in
the paint that are harmful if ingested. Take all
necessary precautions required before painting
or repainting this vessel’s hull.
Some bottom paints contain metals that can
cause corrosion of outboard engines. Leave a
minimum of 3/4” unpainted surface around
all engine parts. Use only paints specifically
designed for aluminum engines as anti-fouling
protection.
!
CAUTION
NOTICE
Painting this vessel’s hull will adversely
affect the boat’s speed and performance and
may require re-propping if the maximum
engine RPMs drop below the engine model/
manufacturer recommended operating range.
