Painting of the drive
Most countries have legislation which regulates the
use of growth inhibiting paints. In some cases, their
use is completely banned on pleasure boats. Ask your
Volvo Penta Dealer for advice on alternative methods
in this case.
IMPORTANT! Find out about current legislation
for painting with growth inhibiting paints / anti-
fouling paints.
The drive
The top coat is part of the corrosion protection of the
drive, and it is important that any paint damage is re-
paired.
Sand metal surfaces lightly with 120 grit emery paper,
and use finer paper on painted surfaces. Wash with
cellulose thinners or an equivalent product. Pores
must be filled and sanded.
Paint with Volvo Penta original primer plus a top coat.
Give the paints time to harden.
The drive should be coated with Volvo Penta anti-foul-
ing paint to prevent the growth of weed and barnacles.
Apply in accordance with the directions on the pack-
age.
IMPORTANT! The protective anodes on the
drive and propeller must not be painted over.
Pressure testing
When the drive has been removed, it must be pres-
sure tested to check for any leakage. Use special tool
3810152, which consists of a pressure gauge with
union, and a hand pump.
78. Connect the pressure gauge to the oil drain hole.
Pump the pressure up to a level not exceeding
78 kPa (11.31 psi).
Check that the pressure remains constant for 1
minute.
NOTE! Make sure that no air leakage can occur via
the hand pump.
If the pressure falls, the leakage must be localized by
using soapy water which is brushed over all joints on
the outboard section.
