I think you are going to find that there are no owner manuals for boats. You can get the shop manuals for the motor and if you look you can some times get wiring diagrams and such but for the most part all you get is just a lot of advice. When I bought my 2014 boat there were no manuals.
Usually boat manuals are useless. They usually just talk about the company and boating safety. Maybe what switches do what and so on. Usually an engine manual is what you want. Your engine manual may be located at: http://boatinfo.no/lib/library.html
