The guy who sold me my new '05 SV211 told me they only used one of the two drain plugs, and just left the other in all the time. I can't find the other plug. Was he wrong about there being a 2nd plug, or did I just not look hard enough?
one in the ski locker and i think one on the back of the boat too. In the ski locker there is a plastic panel on the vertical side facing the back of the boat (if my memory is right). remove that and it should be there.
