    I have blown the gaskets on the strainer with pressure from a hose.
    Really don't have a sinking feeling about this setup. I didn't do this but I have opened the valve on this boat while it was in the water. Needed to wash the bilge of mud etc after an accident., as seen in the picture. If any one opened that valve accidentally and didn't know to close it immediately, they shouldn't own a boat, or a bicycle. JMO

    You know they make seacocks that already have this provision in them right?

    It may not be the owner of the boat could be a friend helping out the owner or some kid working in the yard that is not familiar with the arrangement when the boat gets launched. How many times has fuel been put in a water tank or in a rod holder by people who should know what is going on?
    The positive lock should be in place so that it causes someone to think twice before opening.

    Agree. I know boaters that don’t know what a seacock is.

    Here is another I didn't do but work on. No problem. The one I did do, top picture, in my 26. Crash pump has been used and everyone, in my opinion, should have one. 26flush2.jpg 20flush.jpg

    I have never had good luck with those plastic Graco lids. I love plastic in bilge piping but not for a seastrainer cover.

    A tee on the intake before the strainer has a lot of advantages. It is not that complicated. Neither is Travis' seacock.

    I am interested in rigging up something like this for my raw water cooled generator, but my concern is; if I plumb a garden hose to the sea strainer, if the seacock is closed, wouldn't the hose pressure potentially push too much water through the engine, overwhelm the exhaust/muffler and back fill into the cylinder?

    That is a possibility, all depends on what king of muffler and your exhaust hose run. You could just put a valve on the garden hose to slow it down.

    Over the weekend I rigged one up with a bunch of plumbing PVC I had and bought a few small pieces. Someone in the thread said it was the same 3" thread and it was when I took the cap and tried. I do plan to just use the lid when flushing or such, not leave full time. Will put the original back on so all is tight. Should work well. Makes life a bit easy when trying to flush the Cummins, hold the hose and a Bud Light!

    Could you just leave the seacock open, if flow is a concern? Excess freshwater would just go outside the boat.

    Just suck instead of blow. Fill a bucket then suck from it. Also gives you an idea of how much water you're running through it.

    If you have to winterize, just add antifreeze to the bucket.
