Exactly how deep a boat's propeller penetrates the water can make a difference in top end, acceleration and handling. That's a function of drive height (called "X dimension" in marine industry parlance) or length, and in most cases — stern-drive engine or outboard — that height isn't easily adjustable. The answer, at least for an outboard, is a stern jack, which enables owners to raise and lower their motors independently of tilt and trim.

Among the more popular transom jacks is the Power Lift from Cook Manufacturing Corp. The hydraulic unit attaches to a boat's transom and raises or lowers an outboard motor with the push of a button. Rated to handle outboards up to 7,853 pounds, the Power Lift provides 5 inches of vertical travel.

The key to the system is its 12-volt marine hydraulic raising/lowering system, which is waterproof. The outboard's motor bracket is attached the Power-Lift transom bracket, which is equipped with impact-resistant, aluminum-bronze alloy rollers. The rollers permit vertical movement of the engine, even when the boat is underway.

A dash-mounted toggle switch, which actuates the Power-Lift, is standard. Also mounted in the dash, a sealed engine-position indicator gauge is optional.
