Re: Large Blister on Oday 31 Rudder
I will say this one last time; I recommend that you do not drill a hole in your rudder. Siphon the liquid out, and pour some antifreeze in.
That rudder is foam cored (or was when it left the factory) I think you'll find that filling it with ethylene glycol will dissolve the foam and destroy the rudder
The hysterical laughter you hear as you drive a way in your"new" boat ..... is the seller.
