1988 cajun bass boat

I just painted a guys boat and for trade he gave me this 1988 ricky green fishing machine boat for the job. I was wondering is this a good boat it has the lifetime transom and I counted three pumps for the livewells 2 bilge pumps an airater pump and more switches than you can shake a stick at. Does anyone know why so many pumps? I cant even begin to explain all the plumbing to the pumps. Is there a manual that explains all the in and outs of this boat or does anyone know about this boat and can explain I would be much greatfull http://www.bassboatcentral.com/smileys/bows.gif
