volvo waterpump impeller- does this look right?

[skysurfer2010]

I have a volvo 3.0GS (LK) engine. I'm not sure of the brand of waterpump. I purchased the boat last season and am clueless when the previous owner changed the impeller last. I bought an impeller kit and was going to change it tonight. When I opened it up it wasn't how I expected it to look. I expected the impeller to be centered inside the water pump, but it's not. The sprocket the impeller goes on is positioned off center towards the top. The veins on the impeller barely have any clearance towards the top and are squished. I've had no cooling issues. Is this normal? I downloaded the owners manual but the pictures aren't clear enough to see if that's normal.

If it is normal, does the impeller look like it needs to be changed? It looked to be in good condition to me. The rubber didn't look/feel brittle, all veins are there, and all the tips are still round (no flattening). Or should I change it anyway? Any tips on getting that sucker out? It was in there pretty tight.

the fins should all go the same way after the impeller is used for a few minuets..did you remove it.
in any event, if you already bought, you might as well replace it, better safe than sorry and then you know its fresh.

That's how it looked as soon as I took the cover off. I didn't move it or take it out. I've had no cooling issues. I was going to replace it with a new one, but then I was curious as to if that's normal for the impeller to be off center inside the water pump? No sense in putting a new impeller on if something is wrong.

Yes, it should be off set like that. If it wasnt then the pump wouldnt pump.

All of the fins should be turned the same way. Amazing its stayed like that.

Thanks for the info! One less item I have to worry about. Would you guys still change the impeller if it looks ok? Rubber feels good. No flattening on the ends of the veins. Or is this one of those things you replace regardless of how it looks?

I'm also really glad I bought a Volvo. The impeller took 2 minutes to get to. Removed the two hoses going to the pump and unscrewed 3 screws on the back of the cover.
