- Removed from a 1985-1986 MerCruiser 470 S/N A560005
- Overall Good Condition, water pump seals should probably be replaced since you will be buying new gaskets for anything anyway. (Purchase 27-68714A7)
- There is some evidence that someone replaced the seals in this and installed them in the wrong direction... There's like a chip of material missing, but nothing that would have any impact on function... Again, just make sure to put the seals the other way when you get new ones.
- Front Cover Assembly 71903A2
- For the most part it seems these parts were used from 1976-1989 on pretty much all of the 470 models.
