    Put your head down there and see where it is leaking. Does it get cold enough in your garage to freeze? Maybe rusted out freeze plug.

    Perhaps someone opened the block water jacket drain cocks before it was "laid up" last ?

    Maybe removed the drain plugs on each side when you stored it away and forgot?

    Come on, this isn't rocket science. Get your head in there and see where the water is coming from!

    Or the water froze and the freeze plugs were pushed out by the ice....... by design, this helps to prevent the block from cracking due to freezing.....but not always

    The holes in the block have nothing to do freezing weather and plugs being pushed out by ice. They're there for casting purposes when the block is sand cast. It's just a core plug. A block in a freeze will crack wide open with the plugs still in it.

    Yep. Just because it may have popped a freeze plug, its no guarantee that it didn't do more damage.
    If it gets cold enough to freeze where that boat was stored, consider yourself lucky of the block isn't crack. You simply dodged a bullet.

    Water freezes at 0 degrees Celsius and 32 degrees fahrenheit even if it's only 2 days if there's water in the block from not being winterized and it gets cold it will freeze . The red sand has probly been in there for a while and you need to flush the block if it's not already toast.

    The red sand you see is most likely RUST!

    Don't be sorry for that.

    Are you able to take a picture and post it?
    That would help a lot.
