It looks like a adhesion problem with the paint. The plastic filler will probably not hold the topcoat paint equally to a well prepared aluminum substrate. Your solution is a slip-on stainless skeg guard. I installed one on my engine as a preventative to damage. Instead of screwing it on by drilling (one) hole as shown in the instructions I laid a bead of RTV in the guard and installed it so as to seal it to the skeg. If I ever really need to get it off, I can but it will be a bugger when that day comes. Looks pretty, matches my prop and causes no performance loss that I can tell.
