Going to change the impeller on my nephews Mercury. He's not sure of the year. It's model # 50ELPTO, SN 1B774951
50hp (3 Cyl.)0G760300 THRU 0T999999, 1B000001 & UP
Mercury part # 85089 10
You buy Mercury parts by serial number, not by year. The reason for this is that Mercury stopped using years so dealers could sell left over unused engines without taking a steep discount.
