| Not sure why you sparked to the aluminum of the boat. Typically, the boat is NOT grounded like an automobile is. You must have hit the positve post to the negative post on the battery.
I saw a guy do that in a service station once. Dropped a 7/8" combination wrench right down on both posts! When the air cleared, the battery was split wide open, the sparks had destroyed the paint on top of the customers fender, and the wrench was vaporized. Gone in less than 60 seconds! Last seen, the guy was heading to the restroom for a wipe! | |
