What are you grounding DC or AC? DC is direct current you would ground to the battery. There is no reason to ground to anything else. With AC it is different. Ground here is to protect you in case of a short. Since there is no ground your only option is to ground to the water (Which is not good) You can ground to shore if you are tied to a dock. Remember to keep neutral and ground separate.

I read an article that said not to do that particular thing because it would cause excess electrolysis on that particular through hull.

My understanding of this area is rudimentary, but I believe the goal is to eventually connect the ground to the bonding system that probably connects most of your brass or bronze through-hulls to your sacrificial anodes. I attached mine to a nut at the base of one of the through-hulls.
The article discusses in more detail and I'm not sure I've yet arrived at the correct solution for my boat and plan to double-check everything at the next opportunity.

So I removed the old diesel and am getting ready to install the electric motor. Was reviewing Don Casey's book and came across the illustration showing the whole DC System being grounded to the diesel engine block.Since that is no longer there what should I ground to?
