Which impeller
 

I've got a Mercruiser 350 MAG MPI but I don't have any marine stores in the area so I have to order online. Can anyone tell me what impeller I need?

Year and serial # of motor?

Year?

we need serial number

Sorry... I knew I needed that info but forgot completely to add it in.

The boat is a 2001 Sanger and I'm pretty sure it's the original engine The serial number is 0(zero)L676198

47- 593621 is mercury part number

boats.net is the cheapest back east

The 47-593621 was superseded by the 4759362T1 you have the one piece plastic housing look closely for signs of wear in the back of the housing and on the metal wear plate replace if necessary. If you need to replace the plastic housing you can purchase a kit that includes part #'s 2,3,4,5,6,7&8 part # for the kit is 46-807151A14 and costs around $80. I always recommend that people replace the entire housing as I said before these are prone to wear, some people chose to swap the entire pump for a brass Jabsco, but that will set you back $350-400. Impeller should cost around $20. by itself.

What parts are replaced for just general maintenance? My guess would be the impeller, the wear plate, and what looks like the two o-rings (3 &7)

Just go to the Mercruiser Website. I just registered my motor and ordered all my parts through them. Worked out great.
