Hi Bud, I can’t say I have done this, but this is my idea for how to proceed. First make a template of the centerboard from something like corrugated cardboard, thin plywood or masonite. Next, drill a small diameter hole through one side of the keel, and part way into the other side of the keel. Then, put the template in the slot and drill through it. Check to see if the template pivots up and down. If it does, great. If not, patch the small holes and start over. By not drilling all the way through to the other side of the keel, you have only one cosmetic repair. Once the holes are in the right place, drill out the holes in the keel and use the template to locate the hole in the centerboard. Use something to back up the exit holes to prevent chipping. I would do what ever it takes to get a drill bit long enough to go through the keel so the hole can be drilled from one side. That way, you could be certain that the pivot pin will go through both sides of the keel. I hope to go to the lake this afternoon. :) If so, I should be able to get you a location for where the pin goes through the keel. There is putty applied to a hole on both sides of my keel from a previous owner's repair. I do not know the size of the pin but I can make a guess at it. As far as the stop pin, I think that is associated with the keel of the M-17. There is a stopper knot in the M-15 pennant. I’ll try to remember to measure the line also. Good luck, Steve R.

I have just acquired a 1983 Montgomery 15. Boat is in fine condition with one exception - the centerboard is not installed and there appears to be no way to do so !!!

(snip)

There is a hole in the board for the pennant line but no hole for the pivot !! It appears to be glassed over (quite professionally!) There is also no hole in the centerboard trunk to hold a pin and no hole for a stop pin either! (Guy just couldn't stop glassing!)

So here's the problem - the holes must be re-drilled -- but where??? Seems like some precise measurements are needed for both centerboard and trunk holes. Also what size bolt/pin ?? What size line is used for the pennant? Looks like 1/4 to 5/16 from the pennant hole(s).

Also I have heard about a stop pin. Necessary? function?

Any help muchly appreciated
