I must say, I have a 2011 21V and just this past weekend out I experienced the same problem. I am not sure what could be causing the block, but I also ohad no luck when trying to empty. I tried the water hose idea, but not the shop vac(probably next), but I was thinking of running a borescope down the hose to check for a blockage. I'm curious to see what I find as the pumps all seemed to work fine and there were no tripped circuits.
I thought all boats pre 09 drained the center bag near the driver.
My obv had only gi so I added the rear ballast and drained them on the rear
Real stupid question, but when you put the floor panels back, could you see the screw heads? Right now, mine are mostly covered with the carpet, and I'd like to keep it that way....
You just comb the carpet back over them. Part the carpet when you start the screws and then comb it back over when you have them tight. (Leave Dusty's Mom out of that one.)
