Not much work done this weekend. I did make a wider hole on the dash to accept the connections for the fish finder.

I used the larger RAM Mounts for the HDS 10. I had to bore out two of the holes in the mounting plate as they didn't line up with the HDS 10 gimbal. I test mounted the unit to ensure it would not hit my windshield, or console. I also made sure my hands wouldn't hit it when I turned the steering wheel. Because the dash is just a touch over 1/4 inch of fiberglass and wood, I utilized (4) 1/4 inch stainelss bolts with washers and nylon lock nuts to ensure this unit will not move.
