These are the anodes and bolts from an older R model Mercruiser.
Are these bolts supposed to corrode along with the anode?
From the looks of the bottom set, it seems that once the bolt corrodes in two, the anode is nothing more than a decoration.
These are not the easiest bolts to replace due to their location and being glued or sealed in place. Also, it probably would take someone a long time, if ever, to realize that the bolt had failed.
I'm wondering if it would be a bad idea to replace these aluminum bolts with something... ohhh, I don't know... that doesn't cost $20.00... per bolt!
I believe they also serve a structural purpose as they bolt the bottom of the transom shield to the transom plate.
I would appreciate someone familiar with the R model Mercruiser letting me know if this is normal wear for these bolts and they were meant to be changed every few years or could there be a missing ground strap. Most importantly, is there some way to avoid spending $40.00... for two bolts!!! lol
