hi i have a centurion hull i'm currently re furbishing . it is has been fitted with a casale v drive . last year i contacted centurion boats via the internet and they wew still operating . the owner of the company told e that my boat was originally designed as a jet hull and was converted to a v drive . it has a slight v with a small flat pad in the middle . i think the boat was built between 1975 - 1980 , hope this helps .http://i3.photobucket.com/albums/y62...on454/boat.jpg
