    I have an operator’s manual for the subject motor.
    Anyone have a digital “Parts Manual”?

    Having one may answer a few questions. One I was wondering
    about earlier today. Under the prop shaft “slip cone & spring”,
    is a lead washer with packing under it. The packing only
    abuts against the gear housing, and does not go into a bore
    like a normal seal would.
    Was this someone’s attempt at adding packing or prop shaft seal that Lockwood 72T’s
    didn’t have?

    Thanks.

    I haven’t opened the gear case yet. Glad to see I won’t need to buy any bearings.
    Unlike the Merc KD4 I just worked on, this prop shaft feels nice. From outside
    appearances, the gear case was well lubricated, and worked it’s way up to
    the water pump! Hopefully that’s all a sign that the gears will be in decent shape.
    Going to take the day off from the shop to go snowmobiling with my son,
    and have him help shovel off my roof when we get back, but who knows,
    I may get out to the garage before dark falls again……. inquiring minds
    want to know what’s inside that gear case! …… just wish mine was already
    as clean as yours in the photo. Thanks!

    In the manual under “Cooling System” it states that
    grease getting into the water pump can be a problem.
    My motor never quite pumping water for the time it
    ran but there was a fair amount of grease in the pump
    when I took it apart to remove any water that may have
    gotten into the gear case.
    I had filled the gear case to the top but now I can see
    where that could be a problem. The early Johnson’s
    have an almost identical pump. Years ago I ran a J-65
    several times a day for a month. I don’t remember how
    often I was adding grease but there wasn’t any sign of
    it getting plugged up with grease. It may be that the
    intent of the large reservoir was to reduce how often
    you needed to add grease but ended up creating another
    problem. The hard line from the pump to the cylinder
    makes the removal of the pump some what of a pain.
    On one of the motors I got it came with the water
    line cut in two using a rubber hose to connect them.
    Although not original this would make pump removal
    for cleaning much easier.
