Impeller Identification

[20pilot]

Hi, I was curious if there is a site for mercruiser to look up impellers. I have a 5.0MPI, Serial # OM669371 Model # MCM5.0L MPI. I am looking to replace the impellers on the water pump. Any help would be greatly appreciated.

Thanks

Re: Impeller Identification

More knowledgeable people will chime in shortly, but the impeller required is based upon your outdrive, not engine.

Try this link and plug in your s/n listed then you can choose the various systems in the drop-down box 1 of which is "Sea Water Pump Assembly" and there you'll find the part number for the impeller....along with everything else:

The serial shows up as having a Bravo drive so you would have the engine driven seawater pump. You can get it here Water Pump Kit for Mercruiser 46-807151A14, GLM 12088 - Sierra 18-3150 - iboats if that is correct.

Correction, the kit in the link is not the correct impeller kit. It is for the older models that utilizes the plastics impeller housings.

20pilot's engine would need impeller part number 862232A2 also available here on iboats. 862232a2 - iboats

But if for some reason the impeller housing has become deeply scored then you may need to order a new impeller housing from a Mercruiser dealer if you cannot machine out the deep grooves due to the later model brass housings are unfortunately not available here on iboats.

Here is your OEM parts for you,
