Stuff with bass boats is never simple and straightforward. All the parts wind up being custom, weird, or hard to find. If you want to pay piles of money and have people install stuff for you yeah, that makes it easy. But if you want to do it yourself and you're like me and have never dealt with these kind or rigs before it's going to involve some homework.
That's why I post this stuff, to save other people the hassle. The amount of actual good information on some of these topics like 36v trolling motors that is available online is kind of sad.
