I installed a new A2 stainless steel impeller and new wear ring in my LEGEND PUMP

I now hear and feel a Viberation at idle. When i put on a little or any type of load the noise is gone, but I feel a slight vibration throught the hull.

Is this because the stainless is out of blance? When I had the Aluminum in, their was no vibrations at all.

ya i have this same problem mine is an aluminum impeller, checked the bearings in the pump and the coupler u-joints they all seem good, goes away when the engine warms up and reaches propper idle speed it seems, i think it may just be ware in the splines on the yoke that connects to the pump input shaft.

Hey Sandbar Kid
I'm not being ignorant but did you check the clearance between the impeller and the wear ring , is the wear ring installed true ? Shaft is running true and is it tight ? The stainless one is heavier than the aluminum so maybe the weight diff. is causing a vibe ?
You may have to take the impeller off again and check it for balance .
Depending on the amount of vibration , is it just the way it is and you can run it this way ?
Just a few ideas for you . Hopefully there is a good pump person going to give you even 'better info .

Same thing with my boat.
Outlaw in Red Deer rebuilt my pump and changed from aluminium to a stainless impellor. They told me right off the start that the heavier stainless impellor would cause more low RPM vibration than the aluminium. They were right, I have a slight vib. @ idle, it then goes away when you add more RPZooms.

Same here, when idling/warming up, vibration and noise. Here's some food for thought though, it will only do it when I first get into the river and warming up pointed upstream and won't do it the rest of the day. When in a lake it dosen't do it at all.

pretty much any s.s impeller will make some noise at idle. It sounds bad but does not hurt anything as long as it dissapears above idle.
