How do you jump a starter solenoid on wave runner?

To jump a starter solenoid on a personal watercraft (like a Wave Runner), first ensure the watercraft is in neutral and the safety lanyard is attached. Locate the solenoid, which is typically found near the battery or engine compartment. Using a pair of insulated jumper wires, connect the two large terminals on the solenoid directly to bypass it. This should engage the starter; if it doesn't, there may be other issues with the electrical system.
