Bob's Machine Standard Series Hydraulic Jack Plate

Proven quality since 1978, the Bob's Machine Standard Hydraulic Jack Plate is powerful, lightweight, and reliable. These jack plates are used to improve an outboard boat's speed, holeshot, fuel efficiency, and makes navigating in shallow waters easier. Standard Series Jack Plates were designed to keep the least amount of weight on the transom as possible by keeping the pump inside the boat. The result is a unit that is the lightest weight jack plate on the market. Unlike competitors, Bob's Jack Plates offer a one piece design and do not require setback spacers to achieve the proper setback. Standard Series Hydraulic Jack Plates are available in 4", 6", and 10" setbacks.

Jack plates come with the following: Jack plate, pump, wiring harness, 7' hose, control switch, and oil. Includes a limited lifetime warranty on structure, 60 month warranty on pump, and 12 month warranty on wire harness and solenoids.
