Prohibit motorboats and motorized watercraft on Class 2 waters

This bill prohibits the use of motorboats and personal watercraft on Montana's Class II waters. It directly affects recreational users who operate these vessels on designated Class II water bodies. The key provision amends Montana Code Annotated § 23-2-302 to explicitly ban motorized watercraft on Class II waters, replacing a prior exception. This creates a clear regulatory requirement without new enforcement mechanisms or exceptions. The change applies immediately to all Class II waters as defined under existing state law.
