I have a 2002 Hunter 306 and am trying to install a speaker pod in the overhead stainless arch. I followed the archived posts on drilling into the aft starboard tube from the locker to find an access hole in the plate the tube is welded to. After several pilot holes which hit the stainless plate....I dont believe I have an access hole. Does anyone have knowledge of there being an access hole on a 306? Could it be on the port side? Thanks...
