Thanks to all the response to my orginal posting
Revolution fish finder mounting suggestions ?
This is my design
Hope this is helpful
Using the sail mast receptacle
However I detached the original base and crafted a double pivot base with a transducer wire pass through
None of the pieces are glued down especially the cap
Sometimes you might need to take section off to more easily pass the wire
I ran the power/tranducer wire through the sail mast receptacle. The sail mast receptacle unscrews. Although a solid piece of plastic it has a solid divider to form a 2 or 3 inch female end which is placed on the male end that is part of the interior of the hull.
One hole drilled above the divider and a pass through is formed
The whole assembly goes into the sail mast receptacle including the pass through wires
Just
1. 1 2ft piece of 1/2 PVC
2. 1 four-way T
3. 4 90deg elbows
4. a 1/2 cap -drilled
5. 4 spare sections of 1/2 pvc l(like 2 in maybe each)
6. 4 in or so piece of 1/2 in pvc
