Yanmar uses dual seals but the upper "seal" is just a thin rubber held in place by a little steel band and easily pulls off. This is just a last resort in case the main seal fails.
This design makes it impossible to check for cracks in the main seal.
How exactly do you inspect for cracks from below with all the marine life growing on the rubber?


Volvo uses a single seal. Easier to inspect the top but no safety margin. Good luck in case you experience a leak on passage.


BTW: I know the design.

Yes, I expect if it comes down to it the insurance company would not pay if manufacturer's recommendations not followed. Some bellows are date stamped, some Ive not be able to find.

I replaced one of my long overdue belows a few years ago. It was about 15 years old, but still in excellent condition. I put the new one in and saved the old as a spare, just in case. Ive seen the same on many boats.
