I have a new-to-me 1994 Scout center console 17-2' fiberglass boat. There is a perfectly round hole, approximately 3/8" in diameter, drilled into the V of the bow about 6" below the water line. Probing the hole I can feel there is some sort of a wall aft of the hole, presumably to keep water from the bilge. The hole appears to extent straight up towards the deck. Any idea if this is "factory" or some accessory hole someone drilled long ago and never filled. What is its purpose if indeed it is factory drilled? Thank you!
