My buddy just puchased an 07 puma, we were going over his new purchase and realized an oddity…. we went around boat kinda bumping our fists under the rubrail, and came across a section with a bad hollowed out noise… the location of the problem was just under rubrail in section directly even with the drivers console…. It sounded like rivets may be loose… the boat only has 100 hrs… I was wondering if anyone else had this problem or if it is supposed to sound unstructurally secure like that?
