The internet system never fails to amaze me. According to the National
Marine Manufactures Association, there are 11,853,900 outboard, inboard
and sterndrive boats in use in just the U.S in 2002.

Thanks for the straight forward tip.

The National Marine Manufacturers Association keeps statistics like you are

small boats out there.

But run a search on NMMA and see what you find.
