The instrument panel on my O'Day 28 is located at the level of my ankles and is hard to see. I would like to raise it to seat level and add a tach/hourmeter which it does not have. Two questions: does anyone make a coaming box (with or without lid) that would fit the old cutout, and how do I find and install a tach/hourmeter. All of the coaming boxes I have found seem to be a few standard sizes, and I have not seen a low RPM (4000)tach with hourmeter for sale in any of the common catalogs. Do the sending units attach to the wiring somewhere?Thanks for any help you can give me.Wayne
