I looked online a little and they sold a 8842 and an 8842c. I need to look tonight to see witch one I have. Plowin has 1st shot at it then helenL. I will post the model # when I get home from work. There should be nothing wrong with the machine, I removed it when I bought and rebuilt the boat so I never had it on the boat. I did power it up in the garage and it worked fine. I just have no use for it.
