This troubleshooting guide is provided to help you find the cause of common complaints.

Failure to troubleshoot a problem correctly can damage your outboard motor. Improper repairs or adjustments may damage the outboard motor instead or fixing it. Such damage may not be covered under warranty.

FUSE

1. Turn the ignition key to the “off” position. (Remote control model)
2. Remove the motor cover.
3. Remove the fuse case cover and pull off fuse.

4. Inspect the fuse and replace with new fuse if needed.

If you replace a blown fuse with a fuse having a different amperage rating or with a substitute such as aluminum foil or a wire, extensive electrical system damage and a fire may result.
Always replace a blown fuse with a fuse of the same type and rating.

If a new fuse blows in a short time after installation, you may have a major electrical system problem.
Consult your SUZUKI marine dealer.
