    ST3 Hull Extra Drain Plug (not what you think)

    What is the extra hole that is plugged up next to the Venturi hoses? It's barbed and plugged.

    Might add my bilge pump outlet above this. Yes I know I will need an alarm or light to tell me my bilge is on because I wont be able to see the water coming out.

    But why is it there? I think directly above that will be a nice spot for my bilge drain.

    I installed my outlet here, to try and get it as close as possible to the water line...

    That's where we run the second dump for the Fizzle SuperCooler. Thank you to Sea-Doo for making it easier for us haha.

    I updated the pics with descriptions. The unused plugged hole with barb is a 17/32" inner diameter.

    WHY is it there though? we could find many uses but why is it there?

    It's a long dump but I took my bilge up through the intake pipe and tied it under the cover at the front, no holes - stealth pump- and I can easily notice if it pumps any water. Downside is the longer the outlet is run the less efficient the pumping will be.
    A trade off to keep the bilge outlet high and visable.

    Not my picture but the idea is the same , how ever I went a step further and just purchased a 2016 T fitting because the 2018/2019 are reduced to 3/4 as per 2016 they are 1 inch , I like more water running is am running a separate dump .
