Great write up and perfect timing as I am in the midst of my first Bowthruster service and I will start my first C-Drive service soon thereafter!
I think that you may have left a paragraph out of the"C-Drive Underwater Shaft Seals" section. You start a paragraph with "Let’s trace the three seals…" but then you only talk about the outermost seal before going on to extol the many virtues of Molykote 111. ;) I was hoping you could expound upon the two inner seals as well if you can.
