Mercury 200 OptiMax Manual page 69

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 band is broken, replace the fuse. Replace fuse with a new
fuse with the same rating.
