Boat batteries?

hey guys! Long time member....seldom chat, but always enjoy the forums!
Question: what does everyone else use as far as boat batteries???
so heres the story, and my throughts....
So i bought a new boat last year (princecraft Nanook), great experience! love the boat!!!
however, i seem to have a power problem when it comes to my starting or cranking battery. as most do, i have everything except the trolling motor wired to my starting battery.
quick run down:
merc 90 hp requires 1000ca and 800cca
helix 9 with gps, blue tooth to my trolling motor
radio
lights
etc....
starting battery has 1000ca and 800cca.....exactly what is required.
sooooo, if i leave the fish finder on while pounding shorelines for bass....or whatever, using the trolling motor, i get about 2 hrs and the low voltage warning sounds on the fish finder, (i have it set at 12v....which is what is required to start the motor by the specs.)
so why is that???? i've fished with lots of guys, in lots of different boats, and no one ever seems to have a problem?????
some guys run 2 fish finders, the radio, lights after dark, trim the motor a few times....all day and never have a problem starting there boat, and never seem concerned about it????
so i've done my homework, and i'm going to assume, its the cheap, or lower - end battery from the dealer thats the problem, simply because, it JUST meets the requirements to start the motor, and its not meant for the long draw the other electronics are putting on it.
so before i run out in the spring and buy a new battery, i thought i'd ask the experts???
What do you guys use in your boats as far as batteries???? i'm leaning towards the duel mode (cranking/deep cycle) optima Blue Top D31M group 31 with 1125 ca, 900cca 75ha.
Your thoughts please???
