I recently bought a 1983 Sea Ray with Hull Number SER1A9700183 and length 26' 3".  That is about the extent of what is on the New Mexico Boat Title.  I spent several days searching the web and found a Sea Ray 260 Express Cruiser 1982 that looks identical as best as I can tell.  I am looking for a vinyl cover and an owners manual that will help with wiring diagram.  Any advise of changing out stern drive water pump impellers?

The wiring diagram is part of the Owner's Manual. This Sea Ray web site does not have anything (even close) for your boat. Other sites also don't have that document.

It might be possible for Sea Ray corporate to provide a PDF to you if contacted for assistance.

Good luck.

The impeller replacement is covered in the appropriate Mercury manual.

Contact a local canvas shop, or one of these companies to your cover.
