Painting the Drive and
Underwater Hull
Drive
Varnish damages must be repaired before handling
the drive with anti-fouling agents.
Most countries have introduced legislation controlling
the use of anti-fouling agents. The paint with anti-foul-
ing properties must be permitted to use in the waters
where the boat is to be used. Check the legislation that
applies where the boat is to be used. If paint with anti-
fouling properties is not allowed we recommend that
fine Teflon®* is applied onto the propulsion units coat-
ing varnish without previous sanding.
1 Sand down the metal surfaces lightly with sandpa-
per grain size 120. Use a more fine-grained paper
on the painted surfaces.
2 Wash off with thinner or similar.
3 Glaze over and sand down possible pits.
4 Paint with Volvo Penta original primer and varnish.
Let the paint dry.
5 Paint the drive with anti-fouling agent for aluminum
drives according to the paint manufacturers instruc-
tion.
IMPORTANT!
The sacrificial anodes on the drive must not be painted
or treated with Teflon. This also applies to stainless or
bronze propellers.

Underwater hull
All types of paints with anti-fouling properties are poi-
sonous and cause damage to the marine environment.
Avoid the use of such agents. Most countries have
introduced legislation controlling the use of anti-fouling
agents. Always abide by these regulations. In many
cases it is completely forbidden to use them on pleas-
ure boats.
For boats that are relatively easy to get out of the water
we recommend only Teflon treatment combined with
mechanical cleaning several times per season. For
larger craft, this is not practicable. If the boat is in an
area where the water quickly produces fouling, then
anti-fouling paint must probably be used. In that case,
use copper-based paint containing copper cyanide
and not copper oxide.
Tin-based agents (TBT) must not be used. Check the
legislation that applies where the boat is to be used.
Wait for the paint to dry before launching the boat.
IMPORTANT!
Leave a 10 mm unpainted edge on the stern around
the transom.
