Your engine manual will tell you minimum cranking amps required.

Don't have the manual with me. It's the two engine batteries. Do you know where I can access a manual?

Why not look at them and replace the same?

Take one or both to the battery store and tell the guy behind the counter that’s the one you need. Any marine/rv deep cycle battery with at least 600cca should be fine though.

Buy the biggest most powerful one that will fit in the tray

Yep, mine came with 27s. I found 29s that neck down to 27s at the bottom to fit in 27 trays.
Autozone or Advance. don’t remember.

Sorry, for not getting back to this. The dead ones were clearly not the right battery. I ended up finding a sales guy at the dealership that was kind enough to look it up. Spot on with the 27's Thank you!!!

Regarding your "two engine batteries". The 310 comes with two "banks" totaling 3 batteries. The bank with two batteries wired together in parallel, comprises your house bank, and serves as the starting battery for the starboard engine, and also provides power to your cabin lights, fridge, etc. The other bank with one battery starts your port engine, and also powers your helm electronics.

To your specific question these are the batteries I replaced all of mine with.
