The manual is very limited indeed. You need to collect all the manuals for all the various parts. You can get the engine owners manual, and the engine service manual, for example, which are very good. Same with winches, heaters, chargers, radio, electronics, autopilot, etc. All the way down to bilge pumps and vacuum breakers. I wish they had a great schematic for the entire boat, showing electrical and plumbing circuits, but I think you are on your own (an opportunity to help others?). If you have any questions or mysteries, we can try to help. Your dealer may be helpful too...
