I was about...hmmm...17 maybe? We were on the way back from a day of boating. We arrived at our dock on the Weirs Channel. Everything was going fine. I slowly pulled forward into the dock, and as the boat slipped ever so gently past the posts, I, in my 17 year old block of a brain decided "Hmm, this would be a good time to shut the engine off".
Now, I had been driving boats for 5 years that day. But for some reason, decided to see what would happen when you kill the engine to a moving boat, that weighs about 5000 pounds...well, guess what happened to our dock that day
...yeah.. You can't put into reverse a boat that isn't running! DUMAS!
