Thats good info to know in case my motor decides it wants to take over the world too. LOL I do carry two extra batteries with me just in case. I'm in the porcess of runnin some additional wiring so that I can use the Universal Sonar for a fishfinder on the bow too. Once I get that taken care of, I should be able to focus more on the fishing rather then trying to keep the boat on course. Bad part is that now if I'm not catchin any fish, I can't blame it on my boat setup anymore!! LOL
