Boat Cutouts 101 ( cutting out holes for Electronics) 

Good job. For future reference, they make a rasp blade for oscillating saws. It's sort of shaped like a spade and is really rough on each side like a rasp. Pretty sure you can get them at Harbor Freight for a few bucks. I found that to be extremely useful for final trimming of the cutouts in my dash panel to fit the recessed electronics and switches when I redid my boat console.

Thanks for posting. Pretty helpful.

A rough metal file, for those tight spots, I'm powertool freak but sometimes those manual tools save lives. But yeah good job all in all.

The instructions say to use the gasket if you are installing in a location that won’t get wet. And if installing in an area that does get wet don’t use the gasket and apply silicone. Have you noticed any water getting past that gasket since installing?
