I have been replacing grounds and have some terminated under the engine. There are three bolts under the old W40 but only one is grounded. Should the other two be tied into the grounding/bonding?

Leo....those Bolts are holding on your Strut and shoud be grounded...or you will be replacing your strut like I just did!

Grounded or Bonded? I disagree about bonding or grounding the strut. There should be four bolts on the strut. My data indicates that the grounding should be to a separate grounding plate and that the underwater metal that can be isolated, should be isolated (through hulls, struts, shafts, propellers, etc.) My strut was in the grounding scheme and developed serious corrosion. I installed a serious ground plate for the electrical system and unbonded every underwater metal device. No problems since.
I bonded all underwater metal together by soldering to a cooper ground strip that runs from the front of the engine to the mast step. I believe the theory is that will keep all the underwater pieces at the same electrical potential. Soldering eliminates bad connections that can happen with mechanical methods of bonding.
It's been a couple of years since I did that but I think the standing rig is also tied int that. All electrical grounds were ran back to the negative bus.
I'm in fresh water now, so no problems, I hope it works out when we move her to the coast!
And I only can find three bolts?

Thanks Jim....I should have said Bonded....not grounded.
The Strut was connected to the bonding system in the orginal factory design and my new strut is as well.
