If the livewell system worked well when it worked, then replacing it with the same make model is the easiest approach. In reality the main concern is the GPH rating and duty factor and the ideal sizing depends mostly on the livewell tank capacity.
One funny thing about replacing pumps is that when I replaced mine a while back with the exact make and model, the mounting holes were spaced a bit differently. I didn't expect that
