I just purchased a new Garmin 320c fishfinder for my 1988 Revenge 22 W-T WD. I am thinking about flush mounting [the display] on the helm as this would make a clean installation and eliminate the bracket. What else should I consider before I start cutting?

I don't think there are any electrical considerations involved in the mounting location for the display. You are free to mount it in any location in the helm area. Most of the constraints on mounting would be of a physical nature, such as the line of sight to the operator, clearance behind the panel, aesthetics of the panel layout, access the rear panel connections, orientation of the display unit in direct sunlight, and so on.

About the only constraint on the location of the display device of an electrical nature are the length between the display and the transducer. Often this can be extended if the original cable is too short.

I installed a depth finder into my 1987 Revenge helm dash, and will be replacing it this spring with a GPS/Depth unit. You can see a picture of my helm in my profile. I replaced the aluminum dash panel with a textured black plastic and there is actually a lot of room behind the dash. Cutting the original aluminum panel will be more work, I needed to move things around to make room and add the stereo remote so the 1/4" plastic was the way to go.....Jack

One consideration is the location of the compass binnacle if you have one. The presence of a large metal mass may require recalibrating the compass. They are notoriously sensitive to radios (speaker magnet).

I agree that flush-mounting is the way to go if there is enough dash space. It gives a much cleaner look and there is less chance of theft.

I also agree with Bulldog that 1/4" Starboard is ideal and is much easier to fabricate than aluminum.
