I argee with AJS.

I had the same problem last fall. I drilled holes, bagged the rudder and let it dry all winter. I then filled the void with foam that comes in a can under pressure by inserting the tube from the can and fill in the void. Then I closed the holes with epoxy (It think).

Water weeped through the filled holes.

I then tried a series of other fast fixes as launch day got closer. Still more weeping.

Finally I did a quick patch job with resin. My boat is 30 yrs old and probably had water in the rudder for a long time.

I will do it right next spring!
