Superior quality has made the Power-Lift the #1 selling transom jack in the world! We have been manufacturing top quality transom jacks longer than most of our competitors have been in business. No short cuts are taken at CMC. Computer aided design and precision machining of the Power-Lift is done totally at our facility so you can be sure to get the best quality transom jack at a very competitive price. The Power-Lift utilizes a totally waterproof 12 volt DC marine hydraulic system that is rated OVER 7800 Pounds of thrust. More lifting capacity than any other transom jack on the market. It is 40% more powerful and much more dependable than electro-mechanical transom jacks on the market. The motor bracket moves up and down on a transom bracket by use of rollers Machined from aluminum-bronze alloy. These rollers are highly impact resistant, Corrosive resistant, and have a high load carrying capacity. Thrust is eliminated by the stainless steel pin through this roller with a self lubricating non-metallic material (G.S.M. Nylatron) used for thrust guides on either side of the rollers. This feature eliminates any vibration or "shimmy" due to load applied from high powered outboards. This patented design virtually eliminates any chance of binding, which is common with other transom jacks.

Features Of Patented Hydraulic Power-Lift®   (U.S. Patent 4,482,330)

1. Made of 1/2 inch 6061 T6 alloy aluminum extrusions and fastened with stainless steel fasteners. Ideal for fresh or salt water use. No welds or castings to break.

2. The dependable self contained and water proof hydraulic actuator has a lifting capacity of 7853 pounds of thrust. More than any other transom jack. You will have no problem lifting even a V-8 motor at full throttle. The hydraulic actuator is mounted inside the structure of the Power-Lift, yet it is fully accessible without removing the engine. There are no hoses to contain, nor will you have to contend with mounting a pump and reservoir inside your boat, as is the need with other transom jacks. The hydraulic actuator is completely self-contained with its own fluid reservoir (eliminates the need for hydraulic tank and hoses inside the boat). It contains a permanent magnet motor for more power and R.P.M.. The cylinder within the actuator has twice the lifting capacity than other transom jacks on the market. It contains a no-leak seal and wiper seal that keeps dirt and water out of the working parts. The system is made of 100% non-ferrous material which makes it impervious to saltwater and freshwater.

3. The patented roller design means less friction, longer wear, less maintenance, and virtually no binding problems which are common with other transom jacks. The roller assembly contains a stainless steel 3/4" pin with aluminum-bronze alloy rollers. The roller is highly impact resistant, corrosive resistant, and has a high load carrying capacity. This patented design virtually eliminates any chance of binding which is common with other transom jacks.
