I am getting ready to reinstall the bearing carrier in the l/u for my 1963 Merc 1000. This was a pain to remove (had to take it to a shop where they ended up using heat and a puller). Any suggestions as to what to use to clean up the corrosion without scratching the metal too bad. I am planning on using emory cloth, or 500 grit sandpaper. Also, do you suggest any lube/grease on the outside of the bearing carrier. The manual suggests thread seal for the retainer ring, but gives no suggestion for the carrier itself. I want to insure that if I have to crack the l/u open again in the future that it will come apart relatively easy. Is the thread seal a type of grease/graphite/lithium, or more of a locktite substance?<br />Thanks in advance.

Re: Bearing Carrier Cleanup

You are definately on the right path by wanting to clean up the L/U before reinstalling the bearing carrier. Using a fine grit emory cloth should clean it up real good. Then you need to apply a liberal amount of triple guard grease inside the housing and on the bearing carrier. That should make it alot easier to remove in the future. Living here on the coast we get alot of stuck carriers. The salt can built up so much that it splits the lower unit.

Thanks cajun! Do you use the grease on only the carrier or on the retainer ring also? What kind of grease is the triple guard grease?<br />Thanks

Re: Bearing Carrier Cleanup

As added precaution, I would put grease on the retaining ring also. You never know when you will have to pull it out again. The Triple Guard Grease is a very good general purpose waterproof grease. It won't get washed away from your parts with water like alot of other greases do. I apply it to just about all of my bolts,nuts, mounting surfaces, and even the splines on the drive shaft(just not on the top). If you have ever had to pry a frozen drive shaft out of a crank shaft, you will realize just how cheap a little preventive maintenance (grease on drive shaft spline)can be.
