I don’t remember ever finding a loose hose clamp. Broken ones, including two on this boat so far, but not loose.
Some people over tighten things. Sounds like some overly cautious soul may have been bitten by that and went too far the other way. But to be fair, there is no obvious ideal stopping point.
Sigh. Now I suppose I will have to go around and check all of my hose clamps. Who knows what new problems that will turn up.
