    Ok that is ok, I understand now what happened. I was envisioning higher up, where the gearcase meets the exhaust housing.

    Most definately, that gearcase needs a reseal. The oil drained out, and water got in. Froze, then expanded and cracked it.

    While every 100 hours might be ok, it should be done just before winter.

    You might be able to have it TIG welded with argon, then resealed. OR, as I said earlier, just buy a replacement gearcase ready to bolt up. That would be the easiest, and likely cheapest.

    Perhaps a member in your area could help out.
