I hate to admit it... but you are right. It's water... caused by repeated jet ski launches at the lake and river last year from my hitch mounted jet ski rack.
Crap.

Ok, question...
This breather tube... can it come out (unthread?) then be extended/replaced with a longer tube (snorkel style)?

Also, is there anything else that could have been damaged by the water?

Thanks!
