There is no thru hull plate/zinc. All these wires seem to be just tying together all the underwater metal part ls to the block/battery and in turn the zincs on the trim tabs.
Bilge is 2 part eurethane
for prep I steam cleaned the crud as best I could.
Then pulled all the wires and stuff.
Went nuts with a d/a with 36 grit then filled 29 years worth of random screw holes with kitty hair type glass filler & d/a again with 36.
Sprayed all the metal mounts,shaft couplers with rust acid prep.
I filled up 2 squirt bottles, one with greased lightning and another with bleach. And purple power in the scrub bucket. Soaked everywhere and scrubbed and scrubbed and scrubed again with red scuff pads. Rinse and dry.
2 part eurethane rolled out and sprayed where the roller couldn't reach.

Electrical bonding: Information from Answers.com
Many small boats are not bonded. If you have a lot of metal fittings esp if they are in salt water (inside the bilge and out) I would recommend bonding everything. If you trailer or have a dry bilge and fittings are dry inboard and don't have any 110 operating appliances plugged in, etc then you can get away without bonding.
It also is suppose to help for lighting strikes. Lots of people argue this but it is suppose to give the charge a place to go (ie the water) . The reality is while it might do this many boats hit hard by lighting loose some/all electronics bonded or not.
FYI...My boat is not fully bonded. If I was building a new boat I would bond everything and have a big heavy copper cable running from bow to stern in the bilge. I would also not wire everything like they did. But what is done is done and it works OK so the effort to fix it has a low priority at the moment on the mental to-do list.
BTW, nice paint job on the engine room. What paint did you use (epoxy, poly? one part or two) and talk me thu the prep process. |
