I have been out of the club and go fast boats for awhile but I remember in Central Florida in the 80-90s it was quite popular...took a mid 60sMPH boat to the mid 70s+- of course at great expense to those poor outboards.......I remember people bragging about having EIGHT whole hours on the juice - they didnt last long past that! But considering the tech advances,etc (in hulls and motors) does anyone bother with the bottle anymore?
