Same here Dudley..

I have a "few " hours in a 310... I just set them manually, they
stayed in sync very well

I have 2500 hrs on the boat, no auto sync, although they make them.

You engage it once the vessel is moving fwd in gear, then use one
throttle (usually the Starboard) and the Port engine tracks the
master..

The 1st sign of engine trouble is the engines going out of sync
without any aparent reason...

Cheers!

Dave

Yes... it can be REALLY irritating..

I have a twin engine boat, same issue... VERY annoying.. to me, and
many others..

Some don't seem to mind.. (?)

Not only the noise, but the vibrations , when out of sync, can be very
annoying as well...

We had a Cessna 337 on our line for charter use at one time. It had a sync
gauge. Strangely enough, whenever I had occasion to fly this bird I always
ended up syncing the props by ear. You could easily feel if one of them was
out even by a small amount of RPM.
