Is there a "time in service" limitation on C/S props?

The Pathfinder originally came with a Hartzell prop. Hartzell specifies a 5 year
TBO for CS props on piston aircraft in your application. It also has either a
2000 hour or 2400 hour TBO, depending on the year of manufacture. The specs also
state that hangaring the aircraft doesn't improve matters enough to justify
increasing the calendar TBO.

The full specs are here -
