To post pics;
At the bottom left of this window that your reading is an orange Post Reply button. Press it and in that new window, top and a little right of center, you'll see a paper clip icon in the toolbar. Press it and then press one of the file buttons and find a pic. In that same panel of that window, you must press Upload to get the pic. When it's done uploading, go to the bottom of that window and press Done. That will take you back to your original posting window and you can hit Preview to make sure your pic will be in the posting.
Hope that works for you !

    So small update as this seems to get at least some views, after initial plug replacement I sprayed wd- 40 down the holes let sit 4 days, found on some other forums that recommended pb blaster and marvel mystery oil both supposedly perform better on a side note apparently a machine shop had done a study and a 50/50 of atf and acetone is the greatest penetrating fluid of anything.

    Sat morning went out pulled all the plugs and sprayed blaster and mystery into the plug holes let sit a few hours and then poured some mystery oil into each valve cover attempted to roll it over and it did!!! also began rolling for a few minutes with the starter to hopefully get some oil up top and clean the components next step is to drain oil ad some mystery a little atf and new oil and attempt to fire get it up to temp and see if block is cracked, if no sign of water and no milky.... oil will drain again and run with new oil and send that off to a lab. In meantime have managed to clean quite a bit of the boat back up somehow an hour of leaving some old wax on the dash brought the bright red right back couldn't believe it.
    every step I get a little more excited I really hope its not cracked and I can revive this awesome boat back to her prestige

    okay so brian i hope you see this and can help as your kinda my good luck charm so far, I went thru as thorough as i could be for start up procedure, down to zinc additives for the cam, so i got it fired up relatively quick start so im happy, however no water in exhaust so i shut it down, exhaust manifolds were warm but not detrimental
    clearly im not getting water so i tried priming the system, i pulled the biggest hose on the four way chamber above the water pump and as fast as i could pour it in i can hear it pouring out the bottom i could have see it, so either i have a huge crack but it looks like its near the bottom of the oil pan and that wouldn't crack or somebody actually winterized this ten years ago by pulling the bottom hose.
    so how do i check and or get the hose back on and get them correctly i seen thread son other forums about getting supply and return backwards... any body with some advise
