What anti-sieze?

[Crocodile]

Hello All,

I have decided on a DIY annual service on my 60hp 2 Stroke Yamaha.

What is a good anti-sieze for the water pump bolts and the top of the driveshaft?

I have done this service before on smaller motors, but I am a bit out of practice.

YouTube offers advice of varying quality.

The good news is that the gearshift rod has a star shape, like a Tork, so no fiddling with tiny screws etc.

Any advice is appreciated.

Thanks

I've always just used a thin smear of grease on the threads
Same as I do for any bolt going into alloy whether it's a motorbike or an outboard and never had a problem with it
Some anti sieze compounds are not good for alloy I believe

I have heard good things about this stuff so recently bought some...

Will see how it goes over time...

Anyone else use it..?

Nickel based antisieze if it is going on stainless bolts.

Thanks for the replies so far.

Permatex has copper in it, which might a problem in aluminium.

How about marine grease?

I've read good things about MolyPaste for stainless bolts into aluminium. No experience with it yet but that's what I have here for my rebuild. Molybdenum disulphide, nickel and bentone - no graphite, copper or lead.

Duralac and Tef-Gel are highly rated for galvanic protection of small fasteners but I'm not sure about torqued-up bolts.

Yeh that might be but they make a nickle based product with no copper in it for this application..

Lanolin grease makes a good poor man's anti sieze and also has a few other uses around a boat.

Duralac used to be the go for dissimilar metals.

Lanolin is as good as anything and won’t introduce any extra galvanic issue.
