DOWNRIGGER APPARATUS FOR TROLLING ABSTRACT OF THE DISCLOSURE The apparatus spools a line carrying a weight for positioning a fishing lure at a desired depth in water for trolling. The apparatus has a motor which rotates a spool carrying the line supporting the weight. A brake automatically brakes the spool when the spool starts to unwind the line, which can occur when the motor is inoperative. Braking force on the spool can be finely adjusted to permit slipping and controlled unwinding, so that the line does not break should the weight become fouled or hung up on the bottom. Preferably, when winding up the weight, a clutch transmits torque between the motor and spool when the torque is below a slipping threshold torque. However, the clutch slips when the slipping threshold torque is exceeded and simultaneously generates an audible warning sound when slipping to protect the motor from overload if the weight becomes "hung up" when winding in. An alternative electrical circuit breaker can be substituted for the clutch to protect the motor.
