So I finally broke down and bought a great condition 2006 TR196 with the 200 EFI 3 liter for me and my son to fish out of. It’s still at the shop getting serviced and a jack plate installed. I like to do things right and want us to enjoy fishing without issues. So I have some questions and hoping you guys will take it easy on me lol. I was thinking about going ahead and switching out the batteries. Would ya recommend lithium all around, not at all, partially etc..? Also, what if anything are your must haves? We will be fishing for fun but also local club/ evening lake tournaments. Thank you in advance!
