Pro-Line Boats 24 Walkarounds Owner's Manual page 20

In addition to providing ideal boat performance, the power trim enables the motor or drive unit to
be raised (tilted up) for trailering, beaching, and launching.
The electric motor that drives the hydraulic pump is protected by an internal thermal circuit breaker
that interrupts the power when overheated. Avoid continued pressure on the switch after the unit
has reached the limits of travel (you can hear the difference in sound as the pump strains against the
increased load).
