Will a Optima Blue Top Battery fit in a stock 29 Fountain Fever group 27 battery holder. I really don't want to replace the battery holder unless there is a holder that will line up with the existing mounting holes already in the boat.

Thanks in advance.

Mike

The way the posts are on the optimas they will hit the box. I imagine that your box mounts to the string like mine does??? I bought Get Real Stringer Plates and then EMI Battery boxes to hold the batterries. The EMI boxes will bolt directly to the stringer plates and work perfect. I bought the set-up off Outdrive Exchange & Performance Marine, they set me up with a great price maybe they can help you out, 623-693-0470
