    I purchased a Mercury mark 20 that I thought was locked up but I have found the problem is the lower unit. I removed the lower unit and now the power head turns over. I can turn the drive shaft on the lower unit back and forth but it will not turn all the way around. I was wondering what special tools are needed to disassemble the lower unit? I was also wondering if a mark 25 lower unit will work?
    Thanks
    Steve

    ]I used this small gland nut packing tool I got off ebay. I had to change the pins but it works. My gear case had the same problem. there is a small magnet in the bottom of the case that had come loose and wedged in the gears.no damage, no problem.

    Thanks for the information on the magnet. Did you epoxy the magnet back to the case?
