Is that some sort of grounding wire? That's really strange...

If the reverse bucket is plastic, it can generate static electricity just from the friction of the water and air. My guess is it is a ground of some kind.

It is plastic, but hasn't it been plastic over the last few years? Why would the new models suddenly need to be grounded out...

My guess! would be a wire, a pathway to connect an unprotected metal to one that has anodes protecting it. It is at a connection for reverse bucket cable. Just my $.02.

I asked the same question from the guy that sold me my leaf blower and that was his explaination. Probably an OSHA or safety thing now.

Some guy got a static shock on a job site once, sued the company, the lawyers make a ton of money, and the price of goods climbs. Got it. :)

My guess it's to protect the metal parts on the bucket from galvanic corrosion since the bucket is plastic. Not the best way to do it, but it I'm guessing it works.

I agree with the wire being there to ground the cable and end for anti corrosion reasons theory. It actually bolts to the bosses on the opposite side of the pump from the anode , probably had some warranty issues with the spring loaded end of the cable corroding and this is a way to avoid that.

I noticed the wire and figured it was a grounding wire too. I didn't realize it was new for 2020 though. At least Yamaha is making a few improvements year after year. I didn't expect anything new but was surprised to find new aluminum wheels with my trailer. Improvements are always nice to see.
:D
