evenrude/johnson are the same motors and suzuki is "almost" identicle but there are a few "minor" differences. all 3 are made by the same compoany and engines are almost interchangable but i cant say for certain.
relays, switches, sensors, add-on parts, and that kind of stuff is about the only place where you see some differences
AFAIK
if you cant get confirmation from lowrance that it will work and how to hook it up then check with the suzuki dealer to be sure, it might just need a plug adapter
