Re: 60HP OMC Lower Unit Screws
You MUST use a "torque" screwdriver as there really is no other way to do the job! Yor place the screw bit in the slot, set it so it will torque the screw off, hold the handle tight and hit the end of the torque screwdriver with a hammer and it come loose just like it was loose already!
You can get one at Sears or any other place where you can buy tools and you most definately don't need the most expensive one they sell. I got mine at Sears for $35 dollars a few years ago so they could have gone up in price, but I ASSURE you it will become one of the most useful tools in your entire toolbox.
In addition, Remove the LOWER screw first when you do the job. there is a "magnet" on the lower screw that is about 1/4" to 1/2" inch long and it will have metal shavings from your lower unit. This is normal. If there are ever "pieces" on the magnet, you got problems! The metal shavings on the magnet are just the regular shavings that come from wear and tear on your lower unit. The magnet catches them all so they don't cause any harm to your lower unit gears.
After you take out the lower screw, screw in the hose for your lower unit lube and attach the lower unit lube to the other end of the hose.
If you take out the TOP screw first, as soon as you take out the LOWER screw, all the fluid leaks out!
After you have your lube hose and lube bottle attached to the lower screw hole, use the torque screwdriver on the upper screw, remove it, squeeze the bottle of lube until it runs out the top hole, put the top screw back in, torque it tight, remove the lube bottle from the lower screw, put the lower screw in and torque it tight and you are done.
