Can anyone recommend a good manufacture of 24 series starting batteries for a twin-engine boat? Engines are 350 mercruisers. My marina recommends a Seahwak 1000 MCA.

Delco makes a really good marine battery. I have 2 Interstates on my boat(came with it) and have had no problems with this brand either for the past 3 years.

Here is a link to a site that helps you decipher the date codes on batteries. It could help you get a fresh one.

There are only 2 or 3 manufacturers of batteries. They make all the various "brands" and just package them differently. So there really is not much difference brand to brand.

BATTERIES

Mako22,
My mechanic swears by Sears Diehard marine batteries! He says they are made to Sears specs. I've never had any problem with Sears batteries in any of my cars or boats. They have always outlasted the warrantees. I also have a 350 in my boat(single) and use the Sears duel purpose batteries (deep cycle and starting) I have twin batteries. Sears stores are convienient and stand by their products.
