If you are close to rinkers I would ask or take by. I think the folks at slalom shop would help out on a boat that new. And if battery is bad you might not be out that much money to swap.

For the sake of not arguing, let's say it is the batteries....Is Optima Blue top the way to go?
3 batteries, 1 for cranking on bank 1 and two for running & house power on bank 2? The two batteries on the same bank, are they wired in series or parallel?2017 Moomba Craz Surf Edition

If I was going to suggest a single cranking and twin battery house setup, the blue top optima would not be my choice, especially for the house side. The blue top 31 is the larges in their stable. Its the same footprint of a 29 or 31 wet cell. Its cost is likelt 2-3 times a wet cell. But what do you get for that cast? Nearly half of the battery amp/hours, IIRC, the optima is like 55-65 Ah. A typicall 29 or 21 is 100+ Ah. So thats about half the play time for a battery thats easily 2X the cost.
So, if an AGM is the best battery type for you, there are far better amp/hour AGM's out there for the money. Id go with an 80ah for the cranking bank and two 100Ah for the house side.
Wet Cells; id go with a group 24 for the cranking and two 29's or 31's for the house .
Either way, if you have an on-board charger. both these options will impact it. Your charger may not be ideal for AGM and it could be on th elight side fo rthat large of a Amp/Hour setup.

I highly recommend the Interstate 31M-AGM for a stereo battery. It’s a dual purpose batt at 100hrs. That’s what I was running in my ‘06 with 4 amplifiers running two Rev410’s, the In boats and two W6’s with everything set on kill!
Never had an issue with it. Price is pretty reasonable too if you have an Interstate shop nearby.Last edited by Broke Pilot; 04-27-2018 at 04:16 PM.

So I swung by Advance Auto and had the batteries tested. They tested just fine
Dropped the Craz off at Rinker's, looks to be an issue with the starter. Warranty work...smdh.

Aww dang... sorry to hear that. Sucks to have to drop the boat right before a beautiful weekend. We’re headed out tomorrow and Sunday hopefully. Always lookin for people to join us if you’re itching to get out! Lol

Gents,
Great thread. However, I feel compelled to throw my .02$ in. After messing up with a multi position perko battery switch(forgetting to switch back). I put in a Automatic charging relay. It takes the effort out of battery isolation.-Blaine
