Need bigger batteries, I'm convinced is your issue. I would go up to a group 29 or better yet 31's if you got the room. I can pull cranks on an 18' fiberglass boat for 8 to 9 hours on two Interstate 29's. Takes 15 or 16 hours for my 5amp charger to fully charge those 29's if run completely dead. A 10amp will charge them overnight in 6 - 8 hours.Quote:

DO YOU HAVE THE PRECISION 212 ? I fished 7 hrs. and it takes mine about 5 hrs. to be fully topped back off . Attachment 305829Quote:

Group 27 batteries are not sufficient for that type of fishng!
Go to the 15 amp charger, I got one you can get on the cheap and try it before changing your batts out.
The charging system on your outboard isn't designed to literally recharge your batteries, certainly not repeatedly and if you attempt to do so in time it will fail. Furthermore, I don't think the time your running across the lake would make any significant difference anyway. If your batteries won't recharge overnight then I agree that your charger is to small. I use 15 amp dual pro chargers, one is 14 years old and still going the best money can buy in my opinion.
Everybody always suggest group 31s. However, I barely have room for 2 27s in my express h51. Poor folks have poor ways. I try to stretch my time out by tilting my outboard and running downwind when feasible.

Take the amp hour rating and divide by charger amp output.. then add 10 percent.
That’s how long it will take to charge your batteries from dead.
You want to charge them as slow as possible but at the same time fast enough to be ready from day to day.
I suggest atleast 29’s with 120 amp hour rating and a 15 amp per bank charger.... and also the chargers with battery equalizers. They’ll add a year to you having to replace batteries.
I say this because I battled all that years ago. Fishing all day and batteries not being ready to go next day. It’s aggravating.
