Re: how do I fix a bent skeg?
Short answer: Carefully
Serious answer, 1 large and one small hammer. Use the large one on the back side of the bend and the small to hammer lightly on the bend. Gentle and slow. If it has too much of a bend it will break. If it is not a serious bend, leave it alone, does not hurt anything, serves no real purpose other than a little protection for the prop.
You can buy replacement repair kits that bolt on.
