Axis Wakeboard Boat Forum

I just receive my new 2012 A22 and love it. However, we brought it out and filled the hard tanks up and it worked great. Then when we went out later in the day the middle hard tank filled, but the two rear sacs would not fill up. I can hear the pumps running, but no water it filling into them. Any idea what would be wrong, or how I could fix this?

Check the valves. I bet they are closed.

By that, I mean look into the bilge where the ballast pumps are that fill the rear bags. There should be two valves between those pumps and the bags. If the handle are parallel to the hose, then the valves are open, if they are perpendicular, then the valves are closed.

Oh, and crawl under the boat to make sure the intake through hull fitting doesn't have tape over it. I bought a vlx years ago and had the same issue. The dealer forgot to take the tape off of the bottom of the boat.

Are you saying the rear hard tanks did fill early in the day then they did not later?

I have already checked the valves on the pumps and they are open and the hole is open on the bottom. We had already filled up the tanks with water and the dealer had already filled them up when he water tested it before giving it to us. So not sure why they would all of a sudden stop taking in water. We though maybe they could be air locked, but other than that we have no idea.

Probably a priming issue with the pumps (air). I hate the vented loop system they use. The vent loops are in the engine compartment against the horizontal crossbar that goes behind the rear bench seat. When we installed my extra sacs we totally bypassed the vent loops.

Have tried to turn on your rear pumps to fill while slowly trying to get on plane? Often that will force water in to prime the pumps.
