    Glad you said this. I just noticed and thought something was going wrong. Hitting all my numbers though, so I wasn't too concerned.

    I am getting my annual maintenance items together and found the first post of this thread to be immensely helpful and is keeping me from "reinventing the wheel." I do have one question about the zincs. The thread sizes posted there do not seem to agree with the chart at BoatZincs.com. I will not use zinc as I am in fresh water, but want to ensure I order the correct size.

    Are these the correct pencil anodes for the engines indicated by the red arrows?

    I use four E-2 2" long zincs in my aftercooler and heat exchanger. I use 2 E-1G 1" long zincs in my Fuel/Transmission cooler.

    I can’t seem to find the oil capacity of the generator anywhere. Can someone help?
    Also, do I use the same oil as the boat motors?

    On my Onan 9 KW generator, I budget 1 gallon of oil. Of course, checking dipstick for final volume. I use the same oil as the engines: 15W40 Shell Rotella T4. Buy at Wal Mart.
