Picked up my used 2018 octane 222 today. Noticed this thing moving on the roof like a weather vane. It looks like an upside down boat lower outdrive. Just behind the vent in the picture, and straight up from side vent. If you know, what should I do with/about it ? I also found 2 wrenches,1 for the stabilizers and a smaller one looks like it fits 1/2 inch nut .
