Looks like your dealer has no clue about a marine installation.
which is pretty normal around the world.
yes your ground should be potential free, soo NO contact is allowed between + or - and ground.
the fault can be created in the alternator, startermotor, ecm or any sensor or injector system.
if the system is under warranty they have to fix it.
