Normal Water Drain for OMC V6

[boatgrunt]

I have a 89 OMC with a Chevy 4.3 V6. <br /><br />1) I removed the starboard drain plug yesterday and about a half-gallon of water came out (the exhaust manifolds were already drained). I next removed the port side plug and nothing came out. I spent about five minutes poking around in the drain hole with a coathanger and screwdriver, but nothing came out. The plug that didn't drain did previously have a small leak. Is it ok that no water came out of the port side plug?<br /><br />2) I can't get the screws off of my sterndrive to drain it. They seem to be stuck and the head is starting to strip. Any suggestions?

For the block drain that didn't let any water out I would hook up a hose to the T-Stat housing (where the hose from the outdrive attaches) and fill the block again to see if you get some water to drain out, could be a blocked passage. For the drain screws on the outdrive, I've had that problem and ended using a very large screw driver and hitting it square on a few times with a hammer and that did the trick.

you can pour some lowtox a/f into the hose at the front of the manifold and make sure it runs out the drain ****....

Thanks guys. Forgot to mention that right now, I have my engine apart to replace the cylinder heads and exhaust manifolds. Will try to test as you mentioned when everything is back together.
