Hi all, I have a 370 with 3116’s. I recently replaced the batteries as the old one were 6 years old and shot.
The boat had 4 29 series wet cell batteries. And I put in 4 AGM 31 series.
When I am underway at about 1000 rpm - the colts shout up to 16. If I turn a lot of stuff on (lights, reddot heat, amp etc) the colts go back to the 13’s.
My question is’ what causes this? Is it my battery charger (have stock one), are the batteries too big. Has anyone else see this or had this happen?
Would love any help
