I am into fast boats and have found a site called Scream And Fly http://www.screamandfly.com/home/.
They have some increadable videos created by their members.
The one I really like is called "Outboard Overkill Volume 1". This is the link to the 16 MB video.
It shows a couple of the overpowered boats going over 110 mph!
Check it out as well as all of the others in their Multimedia/Videos section.
