I used to be a battery dealer. You can feel free to start engines from deep 
cycle batteries. It won't hurt them.
They are just relatively large and heavy for a given CCA or MCCA ( (marine)cold 
cranking amperage). My start battery is a U1 size. You can pick it up in one 
hand.

The main reason for a separate starting and house batteries is that they are of 
different type (construction). the starting battery is supposed to give you 
high output (100A ?) for a short time, but it hates to be discharged. he house 
battery should be deep -cycle, I.e. it allows to be discharged quite a bit (at 
least, down to 50% or even lower) without damage, but it does not like high 
output that might be required to start an engine (I don't have an inboard, so I 
don't have the problem).

If you run high current through a deep-cycle battery you may damage the plates.

There are batteries that would work fine in both situations (some AGMs), but I 
don't think you have any of those.

Btw. if you go solar, don't skimp on the regulator. Without one or with a cheap 
one, you can kill the battery in no time. Don't ask how I know.
