I recently removed the masthead float from my 2011 Getaway so that I could clean it.
During cleaning I noticed two things that seemed odd:

(1) The mounting bracket puts the float at angle to the mast. Is my bracket bent or is this how it's supposed to be?
(2) While cleaning the float I removed the screw-on stopper seen in the photo above and I heard the distinctive sound of air being released from the float. Was that just a function of the normal atmosphere in the float having been heated --it's July in Texas as I do this-- or did I need to do something special now to refill this float with air? (That seems unlikely, but since I was asking about point #1 I thought I would ask about this as well.)
(2a) Assuming that the answer to #2 is "No, goofy, you don't need to fill the float with air" then what is the purpose of the screw-on stopper?
Thanks! --Matt
