With a twin engine setup, my intuition would be to go with combined
controls for throtle and gearbox. Two levers are enough to fiddle
with, and in a situation where you want more rpm on one engine than on
the other (such as turning *exactly* in place) you can still use
different engine speeds while controlling the direction of thrust.

It all comes down to what you are used to (and what you want to
learn).

The vast majority of inboard twin engine boats are set up with
separate shift levers and throttles, so that's what most people are
used to. If you want your boat to look like most others, and handle
the same way, go with that layout.

Ouboards and I/Os are different. Most of them have single lever
controls.
