Are we talking true "marine deep cycle" or "marine starting"?

I'm guessing you're talking about a Group 24 or Group 27 marine battery.

I don't see a problem with it. Heck, if it works to crank over the engine in a boat, don't see how it would fail to crank over the engine in a Honda.

I'm a firm believer, given space limitations, in plus-sizing battery CCA where possible in my vehicles.
