regular. I don't know why he used deep cycle to begin with, unless he
was possible using one on the cabin side so it could be drained flat
and recharged. Or for some reason was using a trolling motor.

regular ought to do you fine.

The Key West came with a deep cycle. The Proline came with two regulars. I
don't know why that is, but that's the way it is.

I don't, and won't, have a trolling motor on the Key West, so don't know
why it came the way it did. Maybe the manufacturers just consider it an
upgrade or sorts?

Could be John. I have two bat. on my 23' marquis, just regular ol'
$29.95 L-cheapo's. one is the cabin bat. one is engine. through my
own design battery isolator, and unless the engine is running it
seperates both batteries.

running the 500w stereo, the wife's TV and I 've got 8 headlights
I've rigged on a pole for night swimming. I've run the cabin bat.
close to flat dead, and it recharges well. I really don't see any
need for a deep-cycle battery.

Evidently different engineers have different ideas.
I have my own ideas, but they don't listen to me.

Maybe for the better.
