I am buying a boat. The issue I have is that this boat looks like there is a small amount of damage to the gel coat. I can't tell if it actually damaged the fiberglass or just the gel coat. He states it's only the gel coat. Also The guy i'm buying it from says he had the motor rebuild, which cost 7k with 0 hrs on the motor now, which will take around 4 hrs under 35oo rpms to break in. He has reciepts and everything, but i'm just worried that there's actually damage to the fiberglass. What do you think?
