I ran 5+ years on a costco deep cycle in my old boat, and one year of that was the boat sitting dry. (a 
year for fishing, indeed)
Even after pretty much a year without starting, that battery started it right up the next year, and was still going strong when I sold the boat last year.
I have never had a problem with corrosion with any boat batteries. The best thing you can do to make your batteries last much longer is keep them charged. At the end of a trip, where you run it down with a troller, put a charger on it when you get back. Before storing for the winter, charge it fully.
Do that and the battery should last you a good long time. With that kind of battery life for a $50 battery, I think I'll stick with the cheaper ones.
