I am need of a service manual for a 1990 26ft Wellcraft Nova st. I just purchased this boat it was a repo and I have so many questions that I need answers for.any help locating one would be great.

Maybe get the serial number numbers for the engine and drive and order them through a local dealer.

I've found the Clymers to be not very good.

Hi try this fourm they have merc service manuals to down load that will help you with what you need. Go to the merc i/o area then look for the adults only area and you will find it in there. Good luck. http://forums.iboats.com/
