Battery help and advice...

Lotta smart guys on here that know a lot more about batteries than I do.

What batteries (2) would you recommend for my boat? Typical double battery setup with manual switch. Engine is a 350ci.
Usually get Trojans as they are\were rated pretty good, but I only get two seasons out of them (like clockwork).
With the prices of batteries skyrocketing I would like to get this years replacements to last longer and, if possible, not kill my wallet.
