Recently purchased a 2002 merc 25hp
The manufacturer recomend a 465marine cranking amp battery
The group 24 deep cycle at Walmart is 690 marine cranking amps. Can I use a battery with more MCA's then recomended?

Yes. The number of amps is to get the starter to spin the engine at such a speed to fire the engine. If it is too low then there will be undue stress on the starter.

Once I forgot I took the battery out of my boat and went fishing. Ended up taking the battery out of the truck and it was a 1,000 cca. Not nice to carry around a battery that heavy though.
