I need to grab a spare impeller for a 2000 500 EFI but can't seem to figure out which on I need does anyone no the exact part number?

Isn't the 500 just a standard bravo sea water pump? Pretty sure it's like any other bravo with plastic housing.

I have a 2000 502 mag and it utilizes the same impeller as above. I always just buy the entire kit for 76.00 on eBay and it's facrory mercruiser.

That's what I found on line I was just making sure. Not sure our housings are the same.

Mercruiser made the pumps different on the 496 metric motors, but the big block 454/502 etc should all be the same with exception of two piece housings which are now converted to this one piece design.

I will wait until someone with a 500efi confirms, however I'm 99% sure merc didn't build anything special for the 500efi. The pulley is different that's about it.

They are all the same.

Thats the same impeller. I would buy the whole kit though and keep it on the boat. No sense in getting stranded if the housing cracks
