Pull that rusty clamp off and put a cable tie in its
Yea mine have some abrasions from contact also but not terrible. So I’m going to wait.Dont worry about the metal clip, mine rusted away completely- you can put a zip tie on it.
What I cant see much of is the driveshaft bellows. I just changed mine (2004 lift kept fresh water boat) they started to get abrasions by where it contacts the hinge pins and gimbal ring. The old ones were much stiffer than the new ones , exhaust bellows ripped two years prior.
You're on the right track observe and replace. do your annual oil and drive lube changes hit the grease points and watch the rest.
I’ll replace clip with zip tie.
