I just bought a bass raider and I weigh 300Ib and I got in it and was closer to the back and the battery was be hide me and trolling motor any recommendation about we’re do I need to slide my seat or should I mount my battery in front cause the front in was raising and I didn’t feel stable what should I do !

Move the battery forward, and keep it centered. Move your seat forward\back until you find your happy spot. Keep in mind the placement of your tackle box & cooler. Weight distribution is key in these little boats. Keep moving things until you get it figured out.

I'm getting one of these boats in a month or so.

Oh, welcome to the site !
