Through hull Fish Finder Wire Mount

Step by step Grommet install.

I found this grommet at my local Ace hardware for about $4 its for a computer desk or other application where you want to run wires then conceal the hole.

Measured out area, centered grommet and marked.

Drilled out hole with bore slightly smaller than grommet, shaved inside diam with a Dremmel tool until I got a nice snug fit.

Slopped up with some good ol 5200 and slid it into place. I had to mount the Piranhamax base upside down to run the cables through correctly but it worked, I also used a piece of rubber gasket to get an even better seal and flusher mount with the base.
