Nope, epoxy will not harm the ABS. The S in ABS is styrene I believe, one of the ingrediants in polyester resin, that is why it attacks the plastic. (goin from memory here, so cut me some slack!)
But the epoxy will be good. etch the plastic first so it is roughed up a bit, get a good mechanical bond.
I actually remember when that boat came out. Never was popular. Thier version of a drag boat I think.
