Given a starting battery is designed for quick draw-down (starting) and quick recharge over multiple cycles, it can, over time wear down running all your electronics off of it. In such a case, I would say change your cranking battery out with a good dual purpose battery of some sort that has both cranking capabilities for starting, and has the slow draw-down capabilities of a deep cycle. Years ago, there was the "Stowaway" brand that was made like this, and I am sure there are plenty of battery makes out there that will have this capability. Many times they are considered RV batteries.
If you can get to a size 27 dual purpose for your main motor, you'd be all set.
