I called NAPA last night for a price for gasket 18-2887, and they said they did not have it in stock, that they could order it from the mid-west for $5.44 plus $8-$10 shipping UPS, depending on the weight. Around here about $8 is the minimum I have paid for shipping, so possibly around $15.50 each, ( I was remembering it around $20 last time with shipping) unless of course I buy more. There is no marine place here in town anymore, the economy got it. So the closest OMC or marine store is about an hour away from me, so again if I order it from them, $8 shipping UPS. To be fair, some parts I order from NAPA Sierra, they can get in that afternoon or the next morning, depending on if it’s in their warehouse or suppliers that they can pick up on the am and pm parts run they normally do, then no shipping costs.
Mumbles, thanks for the info, I will be checking out those places you mentioned, as I have several tanks to do. And thanks to everyone else that replied too. I think my question is answered.
