I have a 1985 29 mark 2. 

 

Water intrusion problems are a known issue in the mast step.

There is a large, sealed pocket under the mast step that is filled with some
king of semi rigid foam

There is also a very long keel bolt that passes through this "pocket" with a
nut located under the butt of the mast.

On my boat there are drain holes in the rear face of the mast step (located
in the bilge sump)

 

During the sailing season, these drain holes are plugged with screws / caulk
to prevent water ingress into the keel step from the bilge.

When laid up, the screws are removed to allow trapped water to drain out.

If the plugs are not removed, freezing water in the step can cause damage

 

I would look for the drain holes and remove the plugs if you can find them
..... watch to see what comes out.

If you see the drain holes and they are not plugged, I would cautiously
drill them out to clear any debris and let the pocket drain.

I re-drilled mine this fall just to make sure that they were not jammed with
debris.

I can take a photo over the weekend showing the location if it would help
you.

I probed through these holes with a wire and pulled out small bits of dry
foam 

I am lucky and my mast step is perfectly dry.

However, I know other 29-2's are not so lucky.

If you get water pouring out and can feel wet foam in the pocket, I am
guessing that surgery would be required 

Consensus is that water enters the pocket under the mast step around the
front keel bolt
