S Drive And Reverse Gear - Volvo Penta MD2010 Instruction Book

S-drive and reverse gear
The S drive and in certain cases the propeller (reverse gear) is equipped with a sacrificial anode which prevents
galvanic corrosion. Faulty electrical installation can also cause the break down of the galvanic protection.
Damage due to electrolytic corrosion occurs rapidly and is often extensive. For further information see the
chapter: "Electrical system"
IMPORTANT! Improperly applied paint or the wrong type of paint on the keel can put the corrosion protec-
tion system out of action. For further information on painting see the chapter: Laying up/Launching
Oil level. Checking and topping up
Unscrew (counter clockwise) and remove the
dipstick. Wipe off oil. Reinsert the dipstick in the
drive/reverse gear without screwing it in. Remove
again and check that the oil level is between the
MAX and MIN markings on the dipstick. Top up oil
if necessary. For oil quality and capacity: See the
chapter "Technical Data".
IMPORTANT! The oil level should always be
within the MAX and MIN range marked on the
dipstick.
Oil change. S-drive

that the plug o-ring is intact. Replace if necessary.

"Technical Data".
IMPORTANT! If oil is colored gray then water
has entered the drive. Contact authorized
service personnel.
