All this talk about holes in pontoons jinxed me!!
I have been noticing a loss in speed for the past couple weeks and navigating to my slip at Fay's this morning I knew something was up as I felt a lot of drag and speed was way down by about 10 MPH.
Fay's pulled the boat for me and lo and behold another hole in the center tube towards the front nose cone!

Not sure what caused this one yet...
