I towed my boat to the lake with X, like I have done many times. When launching I got in a little too far into the water and my X shut down. The bumper was maybe 1inch into the water. I'm thinking maybe the trailer electrical connection got wet and shorted. I'm nit sure. But the car won't start, says it needs service. Any ideas on how I could handle without Towing and waiting a week+ for service?
