Drive
WARNING! If the boat is equipped with Power Trim Assistant the function must be turned off before taking
the boat out of the water. This prevents automatic trimming of the drive/drives if any test runs are performed
while the boat is on land. For instructions on how to turn off the function please refer to the section “Power
Trim Assistant” in the chapter “Operating”.
Sacrificial Anodes
On the SX and DPS drives, sacrificial anodes are attached to the bottom of the gimbal housing and at the front
of the gearcase above the anti-ventilation plate.
Anodes are slowly eroded away by galvanic action and require inspection. Additionally, anodes that are sub-
jected to frequent wetting and drying require periodic scraping with sandpaper to remove scale and oxidation to
maintain their effectiveness.
Do not paint anodes, as this will destroy their effectiveness. When you need to purchase new anodes, see your
Volvo Penta dealer. Using aftermarket sterndrive anodes may cause cavitation bubbles due to poor fit, which
may lead to propeller erosion.
If additional electronic or electrical equipment is installed, each item should have an individual anode or ground-
ing device and all grounding devices must be interconnected. Follow equipment manufacturers recommenda-
tions.
Faulty electrical installation can also cause the break down of the galvanic protection. Damage due to electro-
lytic corrosion occurs rapidly and is often extensive. For further information see the chapter: “Electrical system”.
IMPORTANT! Always repair damage to paintwork immediately. Improperly applied paint or the wrong type
of paint on the keel can put the corrosion protection system out of action. For further information on paint-
ing see the chapter: Laying up and launching
Replacing Anodes
1. Inspect anodes at each usage. If an anode is 2/3
its original size (1/3 eroded), replace it.
NOTE! The amount of erosion from the drive an-
ode is a good indication of the condition of the
transom shield anode.
2. Remove the two screws holding the anodes onto
the gearcase and/or the gimbal housing. Discard
screws.
3. Remove the old anode.
4. Attach new anode and secure with two new
screws (provided in kit).
5. Tighten screws.
IMPORTANT! Tighten the new anodes so
that there is a good metallic contact is retained.
IMPORTANT! Use zinc sacrificial anodes for salt
water and magnesium anodes for freshwater.
The sacrificial anodes oxidize in contact with air, which
diminishes the galvanized protection. Even a new an-
ode can be oxidized on the surface. Therefore always
clean the sacrificial anodes before launching the
boat.
IMPORTANT! Use emery paper. Do not use a
wire brush or other steel tools when cleaning, as
these may damage the galvanic protection.
