Reply To: Old Mercury Identification

It actually “slings” dirt away, before it can work down into the seal, thus the name, “slinger.” Most every Mercury I can think of had them, up into the 1980s. They are not unique to automatics. Whether you have a Merc or Mark series automatic, the only possible way to install one is to have the power head off, and slide it down the installed drive shaft. A lot of people try to skip out on the power head removal.

Long live American manufacturing!
