Every gasket you need for a complete rebuild by Kyle - Saint Paul, MinnesotaApril 27, 2012
This has every gasket you could need for a complete rebuild of a '78 Mercury 402 motor. They even separate the delicate gaskets for the fuel system into their own package.

Powerhead Gasket Set by Deborah - Whitesburg, KentuckyMay 01, 2012
I am well pleased with the way my order handled and how fast we received it. I got it for my husband and he has put it on the boat but has not had time to try the boat out to see if that takes care of the problem. But we like the service and will recommend this site to friends.
