I m selling my 19' in/out 04 chaparral which has a V6 volvo penta in/out drive. Question im trying to get a ball park figure of value on NADA. It asks do I have a "Transom Jack Hydraulic" I don't know what that is or if I have one. what I have is a power control that lifts the out drive . . is that what transom jack is. thanks
