Full StarFull StarFull StarEmpty StarEmpty Starmissing gasket
by Big from Big Lake, Alaska on September 21, 2013
When I received the package I noticed the Gasket Set had been opened and then taped shut again. Inspection revealed that the Carb to Block gasket was missing. Luckily I was able to reuse the old gasket but was miffed that I had to.

When I ordered the gasket set, I was told it wqould ship the same day, I was told if ordewreed in the next 10 0r 15 minutes it would go out imediately, I had to go to a dealer and get it in a short time so I could get the motor repaired as was promised. Thank you

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.

All the gaskets were correct except the power head gasket. I had to purchase the correct gasket for the power head for $8.50 at my local marine supply.

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.
