what is Quicksilver Perfect-Seal?

[ron7000]

Came across it in the service manual.<br />Asked about it at merc marine store, they didn't carry it.<br /><br />Is it a white paste, like the PTFE paste used in plumbing and air fittings?<br /><br />What are all it's applications? My service manual said to use it on the cylinder head bolts.<br /><br />And is there an off the shelf replacement for it?

it is a brown thick liquid gasket sealer.liquid permatex or indian head gasket shellac are the closest to perfect seal.as far as applications ,use any where a gasket sealer is desired.

The Mercury product is also the same as the Johnson-Evinrude Gasket Sealer (about $3.95) and in the automotive trade it is known as Perfect Seal #4.

A drawback of buying the Quicksilver perfect seal is that it is only available in a huge size and high cost. For the DIYer it is enough to last for 50 years. Get the Johnson-Evinrude gasket sealer as seahorse says since it is a much smaller size.
