Generally, when do you use anti-sieze?

[Dshow]

I'll be pulling the risors off my engine this winter and was wondering, when I put them back on, should I use anti-sieze on the bolts?

In general, when is this used? Exhaust system components only? Any bolt that looks corroded and you don't want to get stuck? All bolts?

Thanks- Dshow

Ayuh,... It won't hurt nothin'.... I use it on All lugnuts,... Sometimes on sparkplug threads...

Not much Saltwater in Indiana,... You shouldn't have much of a Corrosion problem...

in saltwater DO NOT use any anti-seize using copper.
nickel tin mix only.
I only use it when I may be the next fool to try to remove the fastener and some hulls I have worked on about 20 years.

I wouldn't use copper based anti-seize around aluminum anyway. I use the Permatex silver colored stuff generally for steel to steel.

But where bolts and studs go into aluminum threads, such as on the lower unit, Mercury seem to recommend their Perfect Seal, which is similar to Permatex Aviation sealant, a soft brushable non-setting gasket sealant. I guess it keeps water out and therefore prevents corrosion.

I restore cars and almost always use some sort of anti-seize. I never have a problem removing fasteners, even after 10 years or more. The Permatex anti-seize would be ideal for exhaust studs.

I use Permatex, NAPA, or other brand anti-seize on electrical crimp connectors. Although aluminum silver stuff is my mix, it's never allow the connector or wires on the trailer or boat to corrode. I may start using copper mix on electrical connections now that I found a can of it recently.

Re: Generally, when do you use anti-sieze?

I have used it over the years...the same Permatex silver colored stuff...and one piece of advice I can give...is to not smear a lot of it on the threads...just a very thin coating...if you put a thick coating it can clog the threads and make removal and later re-installation difficult...I learned this on the swaybar bracket bolts on my Jeep...trying to thread them in...they just didn't seem to be starting right...looking closely...the threads were clogged with the silver paste...and at least on a cast iron head...I found that spark plugs actually come out easier if lubed with a little grease...than antiseize...tried both on my Jeep 4.0 and they came out easier using grease or motor oil....now aluminum heads....are a different story...just be real careful if you use a torque wrench...because with antiseize or any lubricant on the threads....the torque has to be reduced somewhat...if you use the standard value...it may be to tight because of the lubricating quality of the anti seize..

On any bolts on the outdrive I use OMCs version of the Aviation Sealer and it really works great...even in salt water...their triple guard grease..also works well too..
