Battery size for Penta aq271

[Brian WV]

Recently acquired a sunrunner 235 weekender and it needs batteries. I referenced the engine manual and didn't see any guidelines as to what size to get. Would something along the lines of a 575 cold cranking amps be sufficient? Any help would be appreciated as I am tryin to fire it up this weekend. Oh the motor is rated for 270 hp. Thanks

Ayuh,... Welcome Aboard,....

I'd consider that the absolute Minimum...

Thank you for the response

I certainly do not want the minimum. Any suggestion on a comfortable cca range?

Ayuh,.... Anything Higher will do....

Or,..
You can run multiple batteries like many of Us do, with a battery switch...
