INSPECTION AND MAINTENANCE

ENOM00088-A

Anode replacement

A sacrificial anode protects the outboard motor from electrolytic corrosion. Anode is
located on the gear case, cylinder etc.. When the anode is eroded more than 1/3 of
original size, replace it.

ENON00029-0

Notes

Never grease or paint the anode.

At each inspection re-tighten the anode attaching bolt. As it is likely to be subjected to electrolytic
corrosion.

*1 : Both side
