Bruce, a lot of twin engine trawlers travel on one engine/shaft from
time to time as a fuel saving measure. Our former trawler had twins and
although we didn't do it as an economy thing, from time to time we'd run
with just one engine/shaft to learn how to steer in the event of a
single engine casualty.
I think you won't gain anything by throwing tires or anything else over
the side to increase drag other than slowing the boat down and creating
a hindrance when you pull along side a pier or enter the travel lift.
The boat will steer perfectly well for turning, straight line, etc, even
through the rudder-angle-indicator may be off a bit from what you would
normally expect with both engines pushing their weight.
You're just going to get an unplanned and quick lesson in single engine
maneuvering, IMHO! I'd sure want to practice backing and filling before
you get to the point where you have to enter the sling just to get a
feel for how she'll handle.

a couple of used tires over the starboard bow or amidships as compensatory
drag.
