Bestchoice for a battery

[Crosbyman]

Time to get a new battery....what is the best size ... cranking amps & type
for a 2005 - 75 hp etec...

Marine starting (smaller size before size 27)
marine starting/deep discharge..size 27
deep discharge only is good enough ? (some boards say to keep away from these for starting because they develop a higher voltage ??)

I think my book said 675ccA for a 115hp E-Tec so I guess the 75hp would be about the same, it needs to be a marine type battery.
