I'm not sure exactly the exact details of what happened John, but the gearbox has seized or stripped. Its off my dad's motor. The motors not really worth spend the sort of money reconditioning or a good second hand one would cost. I'm just putting it out there that hopefully someone will have one I can get at a reasonable price to give him. He's retired in Tully Heads and I'd hate to see him miss a good day out on the water if his other motor goes down
