Anti-Seize Grease or Compound?

[GrahamM376]

Rebuilding an outboard, what's best anti-sieze grease/compound for stainless bolts into aluminium? Wished they had used some on original assembly.

Tef-Gel is good stuff.

Tefgel every time.

I was just about to post the same thing...! Having spent the last 2 weeks trying to dismantle various boat items made of aluminium/alloy including the outboard, I could see the stuff far enough. THere must be a better material to use nowadays!!!!

I'm going to use Tef Gel for the main leg bolts and have put AC-50 on all external moving parts, but the one bit that's go me thinking is the anode bolt. If it's isolated from the leg, its useless. If the bolt contacts the body, will it corrode (given that the anode is attached to it)? Or, should I assemble it with the bolt contacting alloy well, but grease up all around the bolt to stop seawater getting in?

Thanks for advice guys, have ordered some Tef-Gel.

Tef-Gel doesn't electrically isolate the parts.

Renolit anti-seize paste, great stuff but filthy black, wear gloves!

Yup! Checked it withmy meter and anode is connected to the rest of the engine ok.
