I just recently picked up my first jack plate. Itll be going onto my 1982 Procraft 1750 fish and ski. The motor is the original Merc 150 Black Max. The jack plate is a Bobs Machine 6 inch Action series. I have no idea where to baseline the installed height of plate or plate to motor. Currently, cavitation plate is even with keel or bottom of boat. Anybody out there have any info on height? I appreciate the help. Thanks
