    2018+ ST3 Hull Bilge outlet location

    I want to install a bilge pump into my 2019 RXTX, however I can't figure out where on earth the outlet should be. I can't do what some have done and use the ski pylon cap, as I use the ski pylon. If it can't be in plain line of sight I can always rig a buzzer to kick on, but I'm still not sure of where to put the outlet.

    Any ideas?

    I fitted one to my GTX230 and wanted to keep an eye on the discharge so that meant it was not going out the back. I have my hose running up the air inlet hose , same one as the steering cable, and cable tied in place under the cove. No visible outlet. I can take a pic tomorrow. I know I have lost some pumping efficiency given the length if the hose.

    drilled mine on the left side right behind my left foot goes when I'm cruising so I can feel the warm water if I'm zooming along.

    I used the cap for the ski pylon as a bilge pump discharge. This way there is no need to cut a large hole in the hull. It's very easy to install and works perfectly. Water simply rolls right off the back via the existing drains built into the deck, no water gets into the footwells. There is a check valve so no water can get inside the hull. I also added an alarm which sounds whenever the bilge pump operates to warn me of any problem.

    If you're one of the few who use the ski pylon, then simply drill a hole through the deck right below the pylon cap, either to the left or right.

    I've seen no better solution than this for ST3 hulls.
