Alumacraft Boat, mounting Transducer Downrod on Flat Surfaces – TEST

Alumacraft Boats have many areas where flat surface mounting of a baseplate can be done.

Any level area that has a 4×4 inch area that is flat can use a simple sub plate mounting.

Baseplates sit atop the sub plate using one of two mounting methods.

1. Thumbscrews:  a couple of nylon thumbscrews that act as a quick removal as well as a strain relief should the downrod hit something while deployed.
2. Magnetic Switches:  dual 150lb holding strength magnetic switches

Baseplate selection should take into consideration the span, or distance, from the outer edge of the sub plate to the outside rub rail of the boat.  Refer to the drawing below, Dimension D.
