MAINTENANCE

The electrical wiring circuits on the outboard are protected from
overload by fuses in the wiring. If a fuse is blown, try to locate and
correct the cause of the overload. If the cause is not found, the fuse
may blow again.
Open the fuse holder and look at the silver colored band inside the
fuse. If the band is broken, replace the fuse with a new fuse of the
same rating.
