Abstract
Two embodiments of hydraulic control systems for outboard drives that permit the motor to pop up when an underwater obstacle is struck and return to its normal condition once the obstacle is cleared under a controlled force. Each embodiment includes a simplified arrangement wherein the motor may be raised from a normal running condition to a shallow water trim position and will be held hydraulically in the shallow water position. Each embodiment also permits popping up of the motor from the shallow water position when an underwater obstacle is struck. In one embodiment, the motor is permitted to return to the shallow water position once the obstacle is cleared whereas in the other embodiment, the motor returns to its normal condition once the underwater obstacle is cleared.
