Welcome.
Good choice of boat. I owned a 2015 33 from new for 6 years - essentially the same boat.
Not sure you will find the owners manual much help except for the main boat layout and wiring diagram. It does not cover any of the electronics, engine, steering, deck hardware, windlass, bow thruster, pumps and so on. When you get the boat it will come with the basic legally required handbook and all the instructions/manuals provided by the equipment suppliers relevant to your boat. Given the rapid change in electronics, what you get next year may be different from what has been fitted in the past. You can download all the manufacturers' manuals such as the B&G from the internet.
