Ok guys, I have 17' z21. It was sold off the showroom to me in late 2018. So its only been used a little over a year and garage kept. It has 3 interstates for the trolling motor. The cranking is Interstate AGM 1190cr amp. 2in1. The boat came like this from bass pro. The only thing different is, I got rid of the HDS 9"s it came with and replaced them with lowrance live 12" bow and helm. My boat wont start after a short period of fishing. (Pumps on graphs on). To start i need to use the emergency start switch. know these are not the best batteries. I am trying to fix this. I am not looking for lithium answer.lol
Questions?
1. Is this enough power?
2. What do you have of equal power-electronics that works for you?
3. Whats your diagnosis
4. Is there that much power draw from the 9" to the 12"?
