Thanks Idahosurf! Any chance you know where the ballast pumps are located on a '14 A22? My bags came with the boat and I have yet to take them out and explore...

There is a drain pump under the rear elevated area of the locker. Fill pump is located under the rear seat and Vdrive cover. That's adventurous as I've gotten.

Just did this last week. Our fittings kept popping off on the back drain. Did exactly what AJ did and it worked perfectly tonight. My dealer wants me to show their shop guys what I did. So they can start recommending and then changing other axis owners boats. Apparently they have been having this problem for awhile. Umm axis/Malibu are you there???

Hey is it possible u could send me the pictures of the modification I can't get them to load. Thanks I have a A24 with sumo 900's and the rear drain keeps kinking.
Thanks Josh

I don't have my pictures any longer, but just take the couple of screws out of the rear black uhmw piece that covers where the hose goes back down the aft of the boat by the transom. Under there, you will trim your hose and install a 90* quick connect fitting so the output is facing upwards. Then you will install the next 90* quick connect into the first one (they will clip together like they were meant to connect together). This should form a "U" with 2 90* fittings. The output of the last fitting should be right up above the black UHMW cover and basically against the transom. You will likely mpneed to Dremel the hole in the UHMW piece larger to fit the fitting (hose is smaller diameter than fitting). After test fitting everything...take the (2) 90* fittings and use a marine epoxy or silicone to permanently join them. (Don't use too much that it clogs the water passage). Reinstall it all and enjoy having your bags all the way rearward and no more kinks. Drains better too.

Originally I cut rear drain super short to connect to bag with straight quick connect which actually bound the bag and ruined the port and made it split as well as folding bag so it didn't fill completely into rear of locker. With the vents I ran about a foot of hose and a 90 quick Connect and that binded the port and ruined that seam to a leak

For solution in rear I ran a new longer hose well forward into locker and looped back to rear along engine panel divider to a slight turn to go along back wall of stern to middle point of locker to s 90 quick connect in middle of the floor platform at back (4.5 to 5 feet total length ) NO BIND AND COMPLETELY FULL SAC . In front of locker for vent I looped again forward towards bow and then looped back towards rear over the looped hose to port with a straight quicknconnect(about 3.5 to 4 feet length). I cut two 15 inch treated two by fours and placed them on the side of box for vent hose which keeps the length going to port straight in to the port. NO BINDS AND SND NOW THAT SAC IS FURTHER BACK IN LOCKER ONLY A SMALL AMOUNT Of BAG GOES UNDER SHELF, a full 850 fill on my sumo 850's. wakemakers told me about long loops when I 1st replaced my 1st leaking bag, wish they told me that in the beginning on my pnp original install which I guessed on lengths for connections

For drain of mushroom sac I cut length of hose down to about 6-7 inches and changed the quick connect to a 90, no binds or leaks there now and shortening hose got pump off of floor snd no longer in the way of T handle plug operation , previously had 10-12 inch hose with straight quick Connect that badly binded the port and caused leaks cause tension of the vent hose on a bend to get straight quicknconnect attached. now with 90 goes straight in and hose is straight up and down.

I also use kinetic vents to burp sacs and boat plugs in vent and drain holes to hold water in the sac that is full For listing side. O water gets out of bag, stays rock hard full
