water Pump kit

[asr2001]

Hi Guys,

Can someone tell me the exact item number for a water Pump Kit from I boats for a 1971 Mercury 1350 Serial number 3037451. i am looking for the Kit that is complete with the housing and everything, as well as a number for just the kit with the impeller. i looked it up but confused myself with all the different kits.

Also is there any other Extra parts that i should always keep on hand for this particular model???

Thanks Adam
