Where is the fuse on a Waverunner?
The fuse is usually housed in the main electrical fuse box near the battery, but the exact location varies by model and year. Check your specific WaveRunner’s manual to confirm the precise spot.
In practice, WaveRunners use a combination of a main fuse and several circuit fuses to protect electrical components. Accessing the fuse block typically requires locating the engine compartment or the seating/storage area, then removing a panel or cover to reach the fuses. Always disconnect the battery before inspecting or replacing fuses and use the correct amperage ratings for each circuit.
Where to look on common WaveRunner generations
The following guidelines reflect where technicians commonly find fuse blocks on many Yamaha WaveRunner models. Model-year specifics can differ, so use this as a starting point and verify with the manual for your craft.
- Engine-compartment fuse box located near the battery, often under the hood or inside the front of the engine bay.
- Fuse block tucked under the seat or behind a rear storage panel in the cockpit area.
- Secondary fuse location in the front glove-box or additional storage compartment on some late-2010s models.
- On older or simpler models, a single inline fuse may be found along the wiring harness near the ignition circuit.
Because layouts can differ by model and year, always consult the owner’s or service manual for your specific WaveRunner to avoid incorrect fusing or damage to the electrical system.
How to safely identify and replace a fuse
Before touching any electrical components, ensure the craft is powered off and the battery is disconnected to prevent shocks or short circuits.
- Locate the fuse box by following the steps above and remove the cover to view the fuses and their labels.
- Identify the correct fuse for the circuit you’re inspecting and replace blown fuses with one of the exact amperage rating specified for that circuit.
- Check for signs of corrosion or loose connections inside the fuse box and on the fuse terminals; repair or replace as needed.
- Reinstall the fuse box cover, reattach the battery lead, and test the system to confirm proper operation.
If a fuse continues to blow after replacement, there may be an underlying wiring fault or component issue that requires professional diagnosis.
Model-specific notes
WaveRunners span multiple generations (FX, GP, VX, and others), and the fuse layout can differ between models and markets. If you know your exact model and year, consult Yamaha’s official manuals or contact a dealer or marine technician for the precise fuse block location and amperage specs.
Summary
In most WaveRunners, the fuse is found in the engine compartment near the battery or in a secondary panel under the seat or in the front storage area, depending on the model and year. Always refer to the model-specific manual, follow proper safety procedures when working with electrical components, and ensure you use the correct fuse ratings to keep the system protected.
