Still rattling
#63
Out of curiosity, with both drives in gear (motors off), have you grabbed each prop and compared the backlash between both drives? Might have to jump the nuetral safety switch to get back into nuetral.
Has the prop shaft carrier been removed and the nit or bolt on vertices shaft verified to still be intact? I had a nut come loose that allowed the pinion gear to drop down onto the driven gears. Still ran though

At this point and if it were mine, I’d drain down the fluid, pull the top and back caps off, remove the shift shaft, cam and detent ball and spring, put the shift shaft back in but leave the fork out, refill and run it, it’s going to be in gear since there’s no shift fork to hold the cone, but if the noise goes away, you know it involves the shift fork/cam, cone or bump rings on the gears...you’re not out anything, just time and lube

I am going to suggest getting two 10' lengths of plastic downspout corrugated pipe (solid kind, not holes), and tape it up to your exhaust to help isolate the exhast/motor noise away from the drive when you are troubleshooting and filming.
I don't doubt you that you hear something in the drive. I can hear something in the video, but I can't discern any details about it.

Although I'm not a drive mechanic I have set ring and pinions in cars . It appears to me by looking at your vid with the top cap removed that there is excessive play between the gears maybe caused by too much preload on the drive gear ? (not sure how the distance between teeth are set on a B1) That would definitely cause a rattle .
