    Circuit breaker sizes-- is there a "baseline"?

    I have a 2002 GS201 Fun Deck with a Yamaha 150HP 2 stroke.  I'm troubleshooting electrical problems (things not working at all).  I've pulled a couple breakers to test and noticed that none of them are marked with amperage.  Is there a baseline or standard for the circuits in a boat?  i.e., are horns 5A?  Are bilge pumps 10A?  etc..   I don't want to over or undersize.    Any guidelines or schematics will be GREATLY appreciated.  I've scoured the internet search engines and have not found any specifics.
