I have a 150hp compared to your 115hp, maybe it charges faster/better? but i run all my recircs,bilge , aerater,electronics includ. gps all day on the starting battery and have never had a problem, YET!!!!! this will be year 5 with the same battery. Had to get two new deep cycles last year though. I think your starting battery was on the fritz.
If I had tons of money, I'd probably have a 21footer and 4 or 5 batteries on board
fishfinders are off when fishing buckets(for the most part ) as i am usually in 4 fow or less but on erie everything is running all day of course only if i have any fish
ps, I'm doing great, how you doin? i hadn't been around for some time, hope to be checking in more regularly now.
Goota get me a feed of perchies,
John
