| OK, time and use conditions will also help determine which battery to get. If like sled, you are using up all of your battery in a day in high winds and rough seas, then I would suggest going to a 36v system, and a 101 lb thrust TM. Wheteher it be a Maxxum, Motorguide, or the new Tewrrova, the 36V system would be your best bet. Why? #1, with the higher thrust TM, you won't have to run it as hard to get the same result. #2, the batteries won't drain as fast.
The best thing to do is compare the reserve on the respective batterys. I have had very good luck with the Lead-acid batterys in the past. Never had a day were I ran out of juice, and there were many days that I used the TM 100% pulling harnesses for eyes. Usually had the AP65 set on 4-6, and using the AP. The last barrteries I had were the Trojan SC225's. Big heavy Group 31 battery. Bought them because I had a gift cert from Gander. $100 each. They also would go all day, and have plebty left when I went to charge them.
I'm not sure on the new tech batterys. I've heard that the Optima's do not have the reserve of normal batteries. But the Optima's are a spiral cell technology, and different from the Trojan AGM. There was a good seminar on batteries on the Milwaukee Chapter website from a few years ago. I'll see if I can find it.
I think the new boat will have either the Remy or Trojan wet cells. Depends if I am down in Milwaukee when I want to get them.
As for the charging of the starter battery. Definatley Sled, add a single 5 amp fully Automatic. Guest makes a good one. No sense in pulling the old one and buying a new multi bank.
