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”. Your drive is protected against galvanic corrosion. This protection consists of two-three layers of paint, sacrificial anodes and ground braids. The ground braids maintain a connection between the different components of the drive. A broken connection can result in the rapid corrosion of an individual component even though the protection is otherwise effective. Check ground braids every year. 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! 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 painting see the chapter: Laying up and launching The drive is equipped with a cone clutch for shifting using a control cable with either mechanical operation or an electric actuator and electronic operation.
Corrosion protection. Checking/Changing Check the sacrificial anodes regularly. Change with new anodes when approximately 1/3 of the anode has been eroded. Tighten the new anode so that there is a good electrical contact. Where boats are kept laid up on land when not in use there is a lower level of galvanic corrosion protection due to the oxidation on the sacrificial anodes. Even a new anode can be oxidized on the surface. Before launching the sacrificial anodes must be cleaned/ ground using an emery cloth. IMPORTANT ! Clean with sandpaper. Use no steel tools (e.g. wire brush) as this will impair electrical protection. Your drive is equipped with sacrificial anodes of zinc as standard, intended for use with salt water. On drives used mainly in freshwater the sacrificial anodes should be of magnesium. IMPORTANT ! Use protective anodes as follows: Zinc for use in salt water Magnesium for use in fresh water Aluminium if the boat is used primarily in salt water and occasionally in fresh water. Changing corrosion protection All anodes are secured with screws. Undo the screws holding the anode. Clean the contact surface and fit the new anode.
