    I've seen gearboxes stuck on so hard you'd think the crank and driveshaft were welded together. Many years ago we stripped an engine so far that all we had left was the crank and shaft & had still had to use heat to part them. By all means attempt to get it apart, & if its just the little dowels then your laughing but if its the shaft to crank you may find you destroy something trying to part the pair. You will need to decide at some point wether your going to wreck something to part it or give in and run the engines until the impellers eventually dies and you have nothing to loose by being brutal with it.
    Its an old engine so eeking out another two or 3 seasons might be the best option.

    Yup but only catch is if impeller finally dies when you're offshore with an offshore wind

    He’d have to be really unlucky, he’s got twin outboards!

    I have watched this Video with some trepidation.

    Previous technician didnt grease the splines on the driveshaft, gearcase was not removed in 4 years.
    Have to initiate the movement with an old kitchen knife to get space for larger wedges!!!!!



    Once it moves bit, may be able to spray some 50% acetone/50% Automatic transmission fluid up onto the splines.

    Further suggestions welcome.
    RELAX, Rum may not be the answer, but nor is water or juice. Now what is your Question?

    The first wedge will be a 'Stanley knife blade'.

    3. Loosen and remove the nuts that hold the lower unit in place.
    Almost every outboard has four nuts holding it.
    A socket may not fit, so use a ring wrench to give good purchase on the nuts, which probably will be difficult to loosen.

    Using rubber mallet to free lower unit

    4. Theoretically, the lower unit should now be free; in practice, it invariably sticks and will need a few taps with a soft mallet.
    Do not hit the flange cavitation plates at the sides or they're sure to break.
    A few taps on the aft end of the gearbox unit, as shown here, is acceptable.

    "Almost every outboard has four nuts holding it."
    Nope, nearly always an odd number - 5 or 7. There is invariably a nut aft, hidden by the anode tab

    Got all 7, including that hidden one.
