Closing out an old issue. I put up with the cb problem all summer, and took it to the boat yard after pulling it out for the season. The problem was exactly as Dave described. Fortunately there was no problem inside the trunk. The cast iron board was sandblasted, covered with several coats of epoxy finish, and should now outlast the skipper.

what you describe reads like classic rusted cast iron ... i hope.
another possibility - when you put the boat away in the fall was the centerboard in the full up position? sometimes the pendent can get stuck along the side of the board if the centerboard wasn't all the way up and was pushed up when the boat was put on the trailer.
did you try motoring the boat into big-ish waves or wakes? this has been known to knock the board loose.
i recommend you take the M17 to a boatyard and have her lifted. you may be able to get the board down after lifting an some careful prying along the aft end of the board (between the board and the stop pin). MAKE SURE YOU STILL HAVE THE PENDENT WRAPPED ON THE WINCH AND CLEATED as you don't want the board to come crashing down.
if this does not work some have used a very thin piece of metal and run this up and down the sides of the board to dislodge 'gunk'. be CAREFUL not to damage the fiberglass centerboard trunk).
once the board is down ... and it will likely be rusty; it must be removed and then sandblasted and re-painted. even if it doesn't look 'bad' still refurbish the board. this procedure is well covered on msog.org and msogphotosite.com. don't put too much paint as you can make the board too thick.
with the board out check the centerboard trunk for swelling. this is to see if the steel punchings are rusting (this is bad). if you see swelling major surgery to the keel is required. this repair is also well covered on msog.org and sean mulligan's person site -

my best guess the issue is a rusty centerboard that needs sandblasting and a new coating.

My '77 vintage M-17 spends the summer on Lake Calhoun in Minneapolis. I launched for the season last week (a bit late) and
took my first sail
yesterday. When I tried to drop the centerboard it didn't move. It is stuck in the up position. I've had the boat since 1999 and this is the first such problem. I did have a problem raising the board a couple of years ago, but that problem went away on its own after a couple of weeks.
I've looked at the photos and diagram of the centerboard on a '78 model on the msog.org website, so I think I know what is inside the CB trunk that I can't see. I thought about pushing a rod of some kind through the pendant opening to try to push the board down, but the hole is not much bigger than the pendant. I also don't want to damage the pendant or its connection to the CB.
Does anybody out there have an idea what might be binding the CB, and what I can do to dislodge it without breaking something?
