You can transfer Lowrance waypoints to Humminbird using Humminbird PC. There are even YouTube videos to show you how.The 898 will fit in the dash, though I believe you need the Bezel fro BCB. I am replacing an X15 with a 998 (same outside size as a 898) and need the bezel.BTW, I looked at the 998 and 898 side by side, and the 998 does have quite a bit more screen. As a current owner of a 797, with SI you want as much screen as possible.
