Bob's Machine Shop Ultra HD Hydraulic Jack Plate, 4 Inch Setback, 300 HP Max

The Bob's Machine Shop Ultra HD Hydraulic Jack Plate is a 4 inch setback hydraulic jack plate built for outboards up to 300 horsepower and 625 pounds. It is designed to improve an outboard boat's speed, holeshot, and fuel efficiency, and to help the boater navigate in shallow water by adjusting the outboard's height and setback relative to the transom.

This is a one piece design, so no separate setback spacers are needed to achieve the correct setback. The hydraulic pump is mounted inside the boat rather than on the transom, keeping weight off the back of the boat and improving handling. The jack plate provides a minimum lift above a standard transom of 7-1/2 inches, with 1-1/2 inches built in and 6 inches of rise. Construction is aluminum and stainless steel for corrosion resistance in marine environments, finished in silver.

The complete package includes the lift, controls, pump, switch, hoses, instructions, and oil. It carries a limited lifetime structural workmanship warranty to the original end user, a 60 month warranty on the hydraulic pump against defects in quality and workmanship, and a 12 month warranty on the wire harness and solenoids.
