Hey Bubba, hold my beer and watch this!!!

I fished in a bass club in Ga years ago. Shortly after moving back to KY, one of the new members bought a new high performance bass boat and didn't bother trying to learn how to run it before fishing a tournament. During the 1st tournament, he wiped the boat out, throwing both he and his partner out WITHOUT the kill switch on. The boat circled back and ran the prop all the way up the partner's body, almost killing him.

It can happen so fast and the damage can last forever.
