we really don't want to ruin it so we're looking for advice.
What do we need to do to make this boat ocean ready?

If you are going to trailer it, not much. If you are slipping it,
then barrier coat and bottom paint are necessary depending on the
slip's water conditions, etc.

Do we need to flush out the engine every time we use it?

It's not a bad idea to do it every time even if you slip the boat.
It's not a complicated procedure, easy to do and it will help. There
are various chemicals you can add to the flush, but in general, it's
not necessary - just throw on a set of muffs, hook up a fresh water
hose and have at it. Doesn't take long at all.

Is there anything we can do/add to the engine so it doesn't
need to draw in water to cool it?

Others have mentioned closed loop fresh water cooling systems and the
fact that they are pricey. Raw water systems are fine if you take
care of them.
