Anti seize lubricants

[Rum_Pirate]

What anti seize lubricant would you suggest/recommend for putting on the splines of the drive shaft of an outboard engine; having dropped the foot and replaced the water pump impeller; to prevent seizing and difficulty in future removal?

See : 'Dropping the foot' thread.

Contemplating Permatex, anyone used it? :

I use carlube marine grease - never had a problem removing my duo props.

I'll bet that you have removed the 'props' more often than 10 years periods.

The splines, that I refer to, are on the drive shaft within the outboard leg.

Same oil as used in the leg?

No. The lower unit has a thicker gear oil.

The vertical drive shaft splines are not lubricated. The section from the lower end is inserted into the shaft from the engine.
It is up to operator whether or not to grease/lubricate the splines. They normally are not disconnected other than to replace the water impeller.

Fairly described here.

If you're replacing your water impeller every 10 years I will have some of that. Meanwhile I've never really had any issue with any of the spline greases and then, any grease is better than no grease.

I use bog standard grease, BUT, I remove the props (on my duo-prop outdrives & outboards) annually.

 

[Momac]

For duoprops I used white grease on the splines. It was claimed to be salt water resistant and was still present when I removed the props .
Previously the marina had fitted the props dry and removing them took some persuasion .
Not sure if the same philosophy applies here .

Lanacote or Lanoguard. They're the same thing - lanolin. If it manages to keep a sheep dry and stick in the threads of my anchor shackle it will stick to an outboard spline.

White grease is only water resistant lithium grease and will be fine, so will any other water resistant or waterproof marine grease.
