Gravel in my bowl
« on: April 22, 2016, 03:32:25 PM »
I finally get my engine tuned up only to find out there is a bunch of gravel hidden in my impeller. Now, not only have I had to fish out rocks and pebbles out of my diverter, but I also found pieces of impeller. Can it be repaired, or does anyone have an aluminium impeller they are willing to part with cheap and send to canada?

It is a 12JE Berkeley with an A impeller.

Being an E pump, super easy to pull the bowl to see how bad it is. It could be pieces of the bowl, too.
Pea sized gravel will usually pass thru. Do you have a rock grate or a loader?

I have a rock grate, and when I say gravel, I mean big rocks. Here is a pic to show you what I pulled out, so far.

Looking for an A, A2, or A3 impeller now tho. I guess now would be a good time to upgrade to a better impeller if I can find one. I haven't had the boat in the water yet, lol.

These are the requirements at the pump.
An "A" looks right for the application

Tom at JBP used to have some good take-outs for a reasonable price.

New ones:

I sucked up some rocks that size last season with a JE pump A impeller. Here's what I found when I replaced it.

If you're going to replace the impeller you will need to also replace the wiring unless you get lucky enough to find a used Impala that will fit your wearing you need to measure to find out

I have actually found a used one that comes with a wear ring, and will still be talking to Tom at JPB this afternoon. I might also have a lead on a guy who might be able to repair it, as long as I find all of the pieces. I'll be tearing it down today...
