rusty leak from impeller? water pump? somewhere else?

[Five O'Clock]

Hello All,

I have a Volvo Penta 5.7GXi-E with about 210 hours and I need a little help. I have a leak from what looks like is coming from the impeller, but I don't think it is... I've replaced the impeller twice since the leak started. After I replaced it the first time, I figured it was a faulty impeller or o-ring, but after this time, I believe it's something else.



In photo 1, you can see the impeller cover, and then the rusty water on the bilge pump below. In photo 2, you can see the impeller taken apart, and a hole at about 12:00 on the base of the pump. That hole, I seem to think is some type of drain or overfill mechanism. That hole/drain is usually at 6:00 but I spun it to take a better look since I noticed the water coming from that, and not the seal after putting the impeller back on.

This problem started at the end of last season, and when I run the boat out of water this year, it's doing the same.... Does anybody know what this could be?

Your help is appreciated!!!

There is a black rubber o-ring in the picture....how old is it?

I have had replacement volvo impellers that come without the new o-ring....resist the temptation of re-using them...

I don't think you should have ANY water come out of that "hole"

Sometimes the pump has to be replaced....

the o-ring is brand spanking new, taken out of the box yesterday... the one I took off was flawless too... I ended up reading that thread after I posted so I think I need to replace the pump. any threads on how to do that?

You may have to call the parts people, and ask if a new pump kit comes with instructions for replacement....Volvo parts usually do...

...or ask the oracle....Don will surely know...
