Volvo 290 DP sealants?

[TEAMFISH]

In the past I've always added a little Permatex # 2 non-hardening sealant to the o-rings when reassembling parts on my out drive. Haven't had a leak or a problem and this recommendation came from two boat shops in my area.
Just wondering what everyone else does. I've heard just a layer of good marine grease has the same results. Putting a new motor in the Skippy and I'm going to go through the out drive while I'm into it.

I use Quicksilver Perfect Seal. Seems to do the trick. Sounds basically the same as what you're using. I have a pint size can that should last me about 14 lifetimes.

I was looking at that product. Seems real close to the permatex. Looks to be Mercury's version

I ve used the Permatex #2 as well in the past with great results.

I use "O" ring silicone grease. It won't expand the rubber

Ditto on the Permatex and got it from two shops too.

Permatex on the surfaces not the orings

Curious as to why you recommend this? O-rings usually benefit from a little type of lubrication before assembly. I haven't had a problem in the past or seen any odd results from permatex being on the o-rings.
