So I bought a Seaducer 21 here and have a few questions . I went to the web page and read the setup instructions . It say's this boat is supposed to be set up as a surface drive . But the boat I bought is setup with the stuffing tube through the bottom of the floor into the strut . Wondering why that might have been done and has anyone else done there's that way and why . If you look at the picture of the boat on the left you can see the stuffing tube going through the bottom .
