Impeller Question

[JoeMc]

Here is a picture of the impeller the guy who was repairing my wear ring replaced took. Does this impeller need changing? I am new to PWC. Would appreciate it if anyone can help.

Nicks don't help, they can add to cavitation. You don't say what motor, but the higher the HP the more critical for a smooth edge. Some carefull filing will clean that up. What's more critical is the end that almost rubs the wear ring. With a new wear ring it should literally just clear if not slightly rub on the ring. If it's worn so there's a gap of even a 32nd of an inch it will cavitate on higher HP motors. Can't tell the ring to impeller clearance in a picture.

It looks like that impeller has seen some machine work; I see a lot of tool marks & the edge at the 9 o'clock position has a lot of distortion, but it's hard to zoom in and keep the detail of the image. I'd get rid of it. Are you riding the 130 HP 2-stroke?

Honestly it’s not bad at all. I wouldn’t worry about it.

I'd love to see the vibration readings in in/sec, dynamic at 7000 rpm. I'll be you its not good for the bearing!

I don’t have any. Ended up ordering a new one and going to another mechanic to replace it
