Best Anti-Seize for use on outboard and general use

[skunther]

I'm tired of battling seized bolts and am looking for an anti-seize that my future self will thank me for purchasing. Any recommendations?

Specifically I am thinking of applying it to windlass mounting bolts as well as outboard bottom end bolts (including the prop nut). I want something that won't make the bolts tend to come off either (would I need to adjust my torque settings when using anti-seize?), as this would be inconvenient when weighing anchor or motoring my family to shore in our dinghy.

Also want something to protect against galvanic corrosion (the bolts in my outboard appear dangerously close to being completely seized).

Experience and thoughts are appreciated.

Tef-Gel (Amazon Link). Don't waste your money on the small tubes, buy a tub it will last forever.

I use Lanocote on SS fasteners in my mast.

But I am in fresh water, so YMMV.

For outboards, I use Permatex #2 for bolts which ensures no water entry into bolt holes and no corrosion.

would I need to adjust my torque settings when using anti-seize?

Technically yes. Torque specs assume a dry fit.
In practical applications.. It depends on the fastener and torque specs. Very small fine thread fasteners can be easily damaged so the tightening tolerance is narrow before you damage threads.
Cylinder head bolts should always be done 100% to spec... With no anti seize.

Anti seize is not really 1 type fits all.
For example Permatex makes Aluminum, Copper, and Nickel Anti seize.
Different products for different metals, different temperatures etc.
I have all 3 in my shop and some tefgel

Torque specs assume a dry fit.

I've always assumed the opposite. Hmm.

I've always assumed the opposite. Hmm.

I believe it depends upon bolt material. See below:

I've been using TefGel since the 90's with good results. A rigger who's been in the business more than 30 years told me he prefers to use clear marine silicone sealant on aluminum rigging (e.g. stainless screws/bolts in aluminum). He said it does the job as well as lanolin-based products (Lanocote, Tefgel) at a much lower price, and he likes that it has a weak adhesive property which helps lock the threads yet is easy to overcome when unscrewing.
