You don't need much power for that Yamaha.
400 cca or 500 cca will do, but no one makes a battery that small.

Your electronics don't look very demanding either.
With no trolling motor, you could get by with any group 24, 27, or 31 deep cycle battery,

I used to swear by Die Hard. Now, my goto is Auto Zone. Best current batteries at a reasonable price, IMHO.

I run two, deep cycle batteries.

Have one Interstate battery date code- 2001 and one Everstart (Wally World) battery date code-2000

Both pass load test in October but swapping out both this year as PM.

Tempted to replace with the same but leaning towards swapping out for Deka Deep cycles. Maybe even going one start and one DC.

One thing for sure....not going AGM unless they give me a “lifetime” warranty.

On AGM #3 in the truck. Not a single one of them made it out of warranty. If they didn’t have a 3 year full replacement warranty I would buy one.

Deka made a good jetski battery and I was happy with the one I had. Then, I switched to Dekas in my car and boat. Had lousy results. One crapped out during the warranty period and the dealer wouldn't give me credit unless I bought another Deka. Even then the new battery would have still cost almost as much as full price.

That's when I switched to a Duralast, and that battery is still in service today.
