You can find them in agm. Pricey! I ran a Universal Battery type in the front of my War Eagle with no problems over 3 years. You know how rough Ky Lake gets. Mine took a licking and kept on ticking. I guess it all depends on the quality of the battery.
I thought about doing this on my Pondtoon, but the battery will not fit in the seat box. I wouldn't mount them outside the seat box as this would take up too much floor space.
