    Jack Plate help

    Has anyone ever heard of a DI HydroJack jack plate? Can't find a serial number or anything on it. I'm looking for a owners manual or anything to find a wiring diagram. It's on a 2000 viper cobra 190.

    If it's a Hydro-Jacker it's made by T&H marine.

    Detwiler Industries made the jack plate.

    Thabks Tom! also, does the hydraulic pump need to have a signal sent to it to operate or can I hook it straight to the battery just to see if it works? I have power to the little black circuit board with the lights and control wires and the dial works but the jack plate doesn't move and I'm getting 12v out of the relay going to the pump but nothing moves.

    The problem is the sensor on the jack plate that sends the signal to the relay board or the board is burnt up. The pump should run with 12 volts ran to the relays one will raise it and one takes it back down just like trim relays. Teleflex/Seastar owns Detwiler now.
