Hypoid gear oil SAE#90

CHANGING GEAR OIL
• Be sure the outboard motor is securely fastened to the transom or a stable stand. You could be severely
injured if the outboard motor falls on you.
• Never get under the lower unit while it is tilted, even when the tilt support lever or knob is locked.
Severe injury could occur if the outboard motor accidentally falls.
1. Tilt the outboard motor so that the gear oil drain screw is at the lowest point possible.
2. Place a suitable container under the gear case.
3. Remove the gear oil drain screw.
OIL LEVEL PLUG
GEAR OIL DRAIN SCREW
NOTE: If a magnetic gear oil drain screw is equipped, remove all metal particles from the screw before
installing it.
• Always use new gaskets.
• Do not reuse the removed gaskets.
4. Remove the oil Ievel plug to allow the oil to drain completely. Inspect the used oil after it has been
drained. If the oil is milky, water is getting into the gear case which can cause gear and bearing damage.
Consult your LEHR dealer for repair of the lower unit seals.
5. With the outboard motor in a vertical position and using a flexible or pressurized filling device, inject the
gear oil into the gear oil drain screw hole.
6. When the oil begins to flow out of the oil level plug hole, insert and tighten the oil level plug.
7. Insert and tighten the gear oil drain screw.
EXTERNAL
ANODE
INSPECTING AND REPLACING ANODES
LEHR outboard motors are protected from corrosion by sacrificial anodes. Inspect the anodes periodically.
Remove scales from the surfaces of the external anode. Do not paint the external anode, as this would
render it ineffective.
COATING THE BOAT BOTTOM
A clean hull improves boat performance. The boat bottom should be kept as clean of marine growth as
possible. If necessary, the boat bottom can be coated with an anti-fouling paint approved for your area
to inhibit marine growth. Do not use anti-fouling paint which includes copper or graphite. These paints
can cause more rapid engine corrosion.
