This product brings a simpler rigging option to boaters with twins that need a jack plate.  In the past you would mount two jack plates, and have to control them individually, normally requiring two switches and two gauges to make sure you kept at same height.

Now via Bob’s Machine Shop’s Double Jac, you will only have to install one pump inside the boat.  It is a high flow pump and includes a flow divider/combiner, so it keeps the twin cylinders in the jack plate lifting at the same rate.

The twin jack plate has a standard engine “center to center” of 30 inches.


47.962″ Mounting Width (this is 30″ on center, the largest) X 14″ footprint)

6 inches of adjustable travel.  6″ of setback.
