The only time you need a deep cycle on a boat is if you have a trolling motor or a house battery bank

I have to disagree, any quality deep cycle battery will do the job of starting any outboard on the market. If you run alot of electronics like me, that's all you want. Personally I run 2 dekaney group 27 deep cycles on my boat. I start a 200HO Etec, have 2 vhfs always on, hds7 gen2 and a elite 5 sounder along with radar, 2 meter radio and tunes, most of the time everything is on but the radar. No problems in 10 years, so far.
