I have just purchased bilge pump to carry on the kayak just in case rear cargo area gets flooded.
A bilge pump is a good thing to carry in your Outback in case you get water inside the hull of your kayak, but it won't reduce the amount of water in the rear cargo area, because the water must be entering the cargo area through the scupper holes. As you pump water out of the rear cargo area, new water will come in the scupper holes, and the water level in the rear cargo area will stay unchanged.
A question: Are the scupper holes in the rear cargo area blocked? If they are, and water splashes into the rear cargo area while you're kayaking, it won't be able to run out, and as the amount of water in the rear cargo area increases, the rear end of the kayak will sink deeper in the water.
If the scupper holes are open, I have no idea why the stern of your kayak is floating so low in the water that water is running in the scupper holes and flooding the rear cargo area. Has a friend with a rude sense of humor jammed several large rocks into the stern of your Outback? Have you understated your body weight by about 150 pounds? Is water leaking into the hull of your kayak, making it float low enough in the water so that water runs in the rear scupper holes and sits in the rear cargo area?
