I'm looking at a lightly used Optima marine battery on Craigslist for 1/2 price. It is a dual purpose deep cycle/cranking type with 870 cranking amps. Is 870 cranking amps sufficient for my Yami 150? I'm going to google it but thought I'd ask here first.

When I bought the boat it had an Optima battery. It was a great battery but it just sh!t the bed so time to get another Optima. This sounded like a great deal so I'm thinking about getting it!

Thanks guys,
Blue
