REPAIRS

The repair kit which comes with the boat is a one part glue
operation and should be used for emergency minor repair. For a
permanent repair, a two part Hypalon glue should be used. This
two part Hypalon glue and patching materials are available from
Mercury Marine.
Small tears and punctures in the air chambers which are
1 cm (0.393 in.) or less, can be repaired in an emergency. Larger
areas, or if the patch will overlap a seam, should be patched by a
professional repair technician at an inflatable repair station.
Contact your local Mercury dealer for the nearest inflatable repair
station.
For the best results when gluing, the relative humidity should be
less than 60%, ambient air temperature should be between
18 °C to 25 °C (65 °F to 77 °F) and not in direct sunlight.
Cut out a patch large enough to overlap the damaged area by a
minimum of 38 mm (1.5 in.) from all sides. Center the patch over
the damaged area and with a pencil trace the outline of the patch.
Apply masking tape around the perimeter of the outlined patch
area to ensure a tight and clean glue line.
Using 100 grit sandpaper or a pumice stone, roughen the patch
area on the boat as well as the backside of the patch. When
sanding, you just need to rub off the protective outer surface of the
fabric until a dull finish appears.
Clean the sanded surfaces with either toluene or tolual cleaning
solvents. Keep solvent off skin.
ONE PART GLUE (EMERGENCY REPAIRS ONLY)
Follow the directions on the cement tube.
TWO PART ADHESIVE
Mix a batch of adhesive according to the mixing directions provided
with the adhesive. Keep adhesive off skin. When the adhesive is
fully mixed, it must sit for a short time to activate the catalyst.
Failure to do so will create poor fabric adhesion.
