Back to more questions somewhat related to the Perkins 4-108. This
sailboat
is a pig to back up. It really wants to prop walk to starboard.

Try pulsing the prop when in reverse.

Set engine speed relatively low, then shift into reverse for maybe
5-10 seconds, then back to neutral for maybe 30 seconds.

You will have to experiment with times.

Place rudder in desiored position.

Not perfect, but it will help.
