    Just looked at a couple 40-H and they have them but the friction plate is a bit thinner. Slightly different part number in the data but basically the same size. Also question on the 44XS. Did you build them with new blocks and with no S/N. Have just obtained a red head with no S/N on engine.

    40H is a different part # in my books.

    All my 44Xs builds had a serial number, the 90 H XXX series on the early ones and the normal B XXXXXX#'s on others. Clones, of course, had production service motor serial #'s.

    Just checked my records... I did work on one with no serial number, but it was used when I worked on it. I didn't build it from new.

    I also replaced a block that had burned down, no water is a bad thing.

    Red Head? Mine were Orange, but anyone can buy a spray can of Allis Chalmers orange. Yes, that is what I used...

    Just curious, what is the assembly match number on case and block on the 'mystery motor' ?

    Hi Jerry,
    The head is orange. The S/N is 90H406 followed by an 8 laying on its side. Did a compression check and all are 155.

    Yup, 90H406 was here... in 2004. It went to +.015" then, full rebuild. Ported to APBA legal spec, Bored, Chamferred, Honed, etc.

    Nice motor as it left here.

    No idea where it has been since the gentleman I worked with sold it.

    Default Marchetti and B Looper

    I have obtained an outstanding Marchetti hydro and will finish the restoration. My choice of engines will be a Jerry Waldman "B" Looper version 2.3 that I will restore over the winter. This is the last version of the Loopers before the introduction of the Z engine. Hopefully the package will bring back some memories. The deck will be red and white and carry W-1. Jerry drove for Quincy in a similar boat. Also added a little engine art! Dog Kay finished a Carter carbed 55-H a few weeks back.

    Sorry; I only ever heard it called a boot in the 60's and 70's. I have seen pictures of Waldman's special banjo gearcases and was interested if he used standard ones too.

    Mercury designed a revised Mercury skeg contour for Waldman and I have a few. Note on this engine that there is a unique adapter between the power head and the "C" tower. It is believed that only 7 were made by Mercury! Paul Christner has one on a Waldman "A" Looper
