However, for most boats there is very little in the way of a
boat specific manual. What you normally get is a packet of
manuals for the individual components. Like the manual for the
engine, maybe a manual for the
bilge pumps, another for the
radio, etc. The manual specifically for the boat usually just has hints for basic
maintenance and starting instructions. Like how to make the boat go forward, and "WARNING: Your boat does not have brakes!" If you are lucky, the manual MAY include a basic overall
wiring diagram. Though high odds are that in the last 15 years, that has been modified, maybe beyond recognition.
My recommendation to people looking for manuals is to look on the web for manuals for each component of the boat. Then, start creating your own
wiring diagram while you fix/modify/upgrade.
