Even if you could find OEM documentation on this ~18 year old vessel, you
shouldn't totally rely in them.

Since the boat is this old, it is time for you as the new owner to 'hand
over hand' all of the systems. This it a good idea, even on a new boat..

You seldom get "As Built" details and the outfitting yard (sometimes a 3rd
party) seem to place things and run wires where ever it is most convenient.
