don't touch the helm and do all the stern adjustments with the

Now, the GB is a whole different story ......

Not mine.

Big engines, big props, lots of torque widely spaced, full length
keel, 60,000 lbs of displacement: Docks like a dream, bow thrusters

The problem with twin OBs and I/Os is exactly as you describe: small
props, too close together. Most people I know treat them as a single
engine and use vectored thrust along with judicious use ot the
throttles.
