I have used the wally world batts for several yrs. I have a cranking batt/everstart for my 60hp and the sticker on it says it was made in 5/06, still cranks good, and the 60 starts w/o much cranking at all. I have a Everstart TM batt from wally world as well, cost about $75-80 where I live. I installed this one this spring as the previous one was not lasting very long on my weekend trips imo, (was a wally world Everstart as well and lasted about 4yrs. On the assumption the one I replaced cost $75 4 yrs ago, that's less than $20/yr for the battery. TM batts do die, so get what you can afford, take care of it by charging it up as soon as you get home from the lake and keep it watered. It'll last you a good while, but like most things things these days, nothing lasts like they use to.
GO BIG ORANGE !
I meant to behave, but there were just way too many other options available at the time.
