Hi guys,
Does anyone know if there's an anti-seize compound that can be used on stainless steel bolt threads going into an aluminum casting? I have my Merc outboard all apart and I had several bolts that would not come out. I want to put anti-seize on the stainless and plated steel bolts when I re-assemble it in case I live long enough to have to do it again in the future.
Thanks
Joe

Mercury has their own product, 92-881091k 1, 8 FL OZ can. Probably comparable to some others that are available. If you decide to use it and can't find locally I have several cans available of $8 +shipping each.

Hi, just use a good water proof grease on the threads. Don't use anti-sieze compound unless you can get the graphite free stuff. BRP, Evinrude, has a product that works well, called tripple-guard grease.

That silver anti-seize is fantastic stuff, I use it all the time, even though it has "legs" (eg, you look and see some on your wrist or cuff, scan the room and see it on half the things you've been near since opening the bottle). Thom is on the mark with the graphite ingredient contained in some formulations as it can cause a galvanic reaction with the aluminum and do just the opposite of what you're trying to prevent.

I've used the silver anti-seize with great results.

My family has been using a product called "Never-Sieze" for generations. My grandfather learned of it during WWII when he was assembling engines for B17's.
The manufacturers motto? "Put it together with "Never-Sieze", take it apart with guaranteed ease...."
It's available from auto parts stores. Unless your using it three times a day, your kids will inherit the nearly full container from your garage. I use it on all my outboards and equipment with great results.

I always used "Grease", I was replacing the water pump a few weeks ago and I was struggling getting the bolt's off (thought they were gonna snap with the torque I had on 'em), a boating friend called to see how I was doing, I told him my situation, and my remedy, he said "UH UH, go get a can of Never-Sieze ya weener, ya only live three block's from the auto store, you're only going to have to go in there again eventually". This guy's outboard's always last 20+ years, so I take his advice. I worked in the "Never Seize", and now the bolt's move like they're in "BUTTER". Well worth the $6, AND the three block walk. Next pump change out won't be a "Fight", that "Main Bolt" had me on the ropes but, I eventually won. A few day's later I stopped by the "Power plant" at work and the mechanic's had a co-worker's engine on the bench with all lower unit bolt's "Snapped" off. He did'nt change out the pump for 5 years, the bolt's corroded in place.

Matt, I had the same problem with my lower unit bolts the first time I took the bolts off two years ago. Three out of the five bolts holding it on were corroded in place and snapped. It must have been years before I purchased the motor since the lower unit was removed and reinstalled. Anyway when I pu it all back together, I used a marine grade wheel bearing grease on the bolts before putting them back in. When I removed the lower unit this past fall, the bolts came out as easy as pie. I didn't use any other anti sieze compound but will keep Never Seize in mind when I remove the lower unit again.

Thanks Guys, I have used grease in the past and it has always worked for me on auto engines. I just thought there might be something special for stainless to aluminum that will be used in salt water. I will head for the auto parts store and look for the silver stuff. Love this website

Never seize and like products are not recommended for marine applications.
If you look at the ingredients, the stuff contains copper and other metals. Put that stuff on there, it sets up a galvanic reaction and over time you will find it has the opposite result of what you are looking to do.
Use a marine grease like the blue stuff most manufactures supply and you should be all set.

There are many different anti-seize formulations, some made for marine applications. Not all of them are the same.
I agree about not using the copper infused varieties in a stainless steel/aluminum application.
Copper, nickel, graphite, silver, zinc are all used in various anti-seize formulas. There are non-metal formulations as well which work well in this application.

I agree Tom. A lot of people put that stuff all over everything and do not realize the harm and work they are creating for themselves or the next guy that has to take something apart if the boat is being used in the marine environment.
Been there done that with a few lower units before.
Grease, NOT [copper-based] anti-seize for salt water application.
If you take something apart and it is covered in a white powdery substance, that is the left over [copper-based] anti-seize after galvanic corrosion.

Juts to clarify some of the terms used in this thread above, the term anti-seize means any of several different coating for metal parts that help prevent them from seizing together for galvanic and mechanical reasons.
NeverSeize is one particular anti-seize product manufactured by OXLIC, Inc.
It is notable that NeverSeize is a NON-METALLIC anti-seize formula and recommended for Marine Applications.

Seems like I stirred up a hornets nest with this one, whodathunkit. Anyway, I went to the Loctite website that Tom suggested and found the Marine Grade anti-seize. It's completely metal free. It's for assemblies exposed either directly or indirectly to fresh or salt water and has a great temperature range. The Loctite item number is 34395 for the 8 oz can. I ordered it through McMaster Carr. There's no MMC part number but it's in stock in Chicago with a 2 day ship to NJ. Thanks to everyone for all the input.
