I have recently purchased a 1998 ski Sanger v210 about a month ago and when I was going under the boat to put my fake-a-lake on, I found this hole/crack. It's white and it feels kinda hard and kinda soft, it's definitely not the gel coat. I'm a first time boat owner and would like to know exactly what I'm dealing with and how I should go about it! Thanks in advance for any replies!
