T&T: Battery recomendation

[loraxt10 at aol.com]

What does the list recommend as a new battery to start my Lehman 120? The owner's manual says 140 amp/hrs minimum. All the battery does is start the engine. Any reason why I would need a "marine" starting battery vs an ordinary car starting battery? Group 24 or group 27 & why? Thanks.?????????????????????????????????????????????????????????????????????????????????????
