Now that's a Dynaplate, by Guest. And it is installed per the factory recommendations.
It is definitely time to take the bull by the horns and remove this old miniature Dynaplate. It's clear that several problems arose in the installation from not RTFM. First the plate is mounted way over on the edge where starboard tacks could well take it out of the water. Second, it's near the center (front to back) of the boat where bottom dragging could remove it and cause a catastrophic leak. It wasn't installed right in so many ways! Guest has a very nice set of instructions which would have served the installer well if reading was among the skills and efforts. No back plate was used. The washers were crushing the plywood. The ground wire was hooked up to the non-shiny bolt (wrong one, poor conductivity). The plate was liberally spread with bedding compound. This destroys a good part of the grounding effect. The backing plate when bedded with liberal amounts of polyurethane will force the seal down the holes. That's all you need. Again, in the instructions. And finally, the bolts having not been protected with antioxidant grease were corroded and had to be sawed off. Well, it's gone and the holes were over-sized and epoxy poured and sheathed. I feel better!
Over-sizing the holes from 1/4 to 3/8 to within an 1/8 inch of the bottom laminate cleans out the hole and makes it ready to pour. I cleaned it out with a air can.
I got working room by removing one end of the fender and dropping the bunk.
Meanwhile, I took this opportunity to run new cables under the bed for the outboard starter. I like things as neat as possible. The previous cables ended halfway under the mattress and ran over the rear dorade baffle. Mine will be completely out of site.
This is the light sentry box that is the brains of the power options.
