The pressure on the gearbox internal parts causes damage. But do not confuse the gearbox and engine. The engine is not concerned with this issue of sailing in or out of gear. So you can still have a Yanmar with another brand of gearbox and sail in gear.

The idea of a shaft brake is a good one. It reduces wear on the gearbox internals on long passages. An even better idea for some sailors is a feathering prop which reduces drag and helps save the gearbox.

Volvo Penta MS2 gearbox must be left in neutral when on a shaft driven prop. It's in the owners manual.

If left in astern, it can jam the cones, and if put in ahead, it will wear the cones.

Philip.
