We had a great boat ride on Saturday, until we loaded up on the trailer. I backed the trailer in, and my wife brought the boat up. She got a bit off kilter, and panicked. Long story short she took the boat to shore beside the boat launch. The prop (14.4 19 aluminum) is damaged beyond repair (warp, and tear), and I will replace rather than try to fix. The lower fin of the Alpha 1 drive took a hit too. It has a gouge out of the fin (see photo). What do I do here? Can I file it smooth and use some touch up paint for corrosion protection? Thanks in advance.
