Which Impeller

[ripped_78]

I am trying to replace the impeller on my 1986 mercruiser alpha 1 and I have no clue which one to get. The sereial number on the bell housing is worn off so what are my options?

It's an Alpha 1 Gen. 1.....
You don't need the serial #.......
You can just shop that by the year.....
I don't have the specific part # for ya, sorry.....JK

Ayuh,........

The Sierra #s are,.....
18-3017 for the Impeller itself,......
18-3217 for the Impeller Repair Kit,(includes gaskets)......
And,
18-3320 for the Full Waterpump rebuild Kit.(includes the Pump housings).......

These can be bought from your Local NAPA as well as On-line.......
