I recently bought an '01 sportsman 180. It came from factory with raw water washdown, fresh water sprinkler, trim tabs, bimini top. Did not come with extra battery or plumbed live well. I am planning on using either a Kodiak P14 round tank kit on the swim step or a self-contained system like "keep alive" under the flip seat. The under seat installation would give me about 23 gallons vs. 14 gallons on the step but would not allow me to exchange the water constantly. I could plumb the existing tank in front of the console but I did that on my earlier 208 adventure and didn't like the sloshing around factor. I would also like to install a second battery and second dedicated switch. Where does the factory install the second battery? The starting battery is now on the starboard side under the rear seat. The oil transfer tank is port under the rear seat. Also, has anyone installed a live bait system under the flip seat? Thanks for any input.
