IMPORTANT: Always carry spare 5 and 20 AMP fuses.
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.
1. 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.
