marine goop for water pump gasket sealent..

[starkizzle]

I am about to put this new water pump on my 72 hydro electric, the videos I watched recommend using a gasket sealent but I forget to get the Johnson evinrude stuff from the boat shop, i stopped at a hardware store and they had marine goop, close enough? anyone have any experience with this stuff? and is that cure time really 24 hours?! I think the Johnson stuff sets much quicker

Aviation gasket sealer or permatex #3

Noone has used goop? Thank you for the reply Scott, I will get some aviation sealer, I just left a job at a airport, so i can go talk to my old boss, a A&P Mechanic and get some sealer, just surprised there is no one who has tried goop

Never heard of it. Will have to look into it.

Goop is sealer/adhesive and works just fine.If I didn't have a healthy supply of permatex av sealer goop would suffice.I also have a sealer/adhesive from Polaris that's excellent but the name eludes me right now.

 

[starkizzle]

you would suggest it for a water pump in hydro electric lower unit?

 

[Scott Danforth]

Goop is just silicone

I'm not sure anything is needed, but wouldn't use anything that cures or sets. Don't want an adhesive, and silicone isn't a good choice -- if for no other reason, could break up and send bits and pieces up the water tube where it could lodge somewhere in a water passage. Guess I would either use nothing, or get some of the OMC or Permatex gasket sealer. JMO.
