MerCruiser 71903A2 71903 470 488 190 3.7L 4cyl Front Water Pump Impeller Cover

Item Details

• 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.

Parts Included

• Front Cover Assembly 71903A2

Compatibility

• For the most part it seems these parts were used from 1976-1989 on pretty much all of the 470 models.
