    Pump?

    I pulled the pump off today and this is what I found. Just wondering what would cause this and if it could be the cause of my vibrations.

    Thanks. Mongo

    Pump looks fine all the vanes are in tact. I'm wondering if my extreme cavitation caused this.

    Mine is ground real thin like that too & it's held up well. Was it sealed with silicone? If not, the water forcing its way through there might have broken that piece off. Also, if you don't have any sealant on the front side of the pump, it might be sucking air, adding to the cavitation.

    Now, on my GPR the pump sections have no sealer on them, Do you really think this would cause it to lose pressure in there? It really seems to fit together real tight.

    Oh yeah, those.Just a guess, but I'd think cavitation would take out the vanes in the pump well before doing damage to the nozzle like that.

    Something broke those vanes I think. You would think cavitation would leave some signs around the edges where it broke.

    It could cause a vibration by the way.

    +1. If you can get a pic of the prop you can see the cavitation burns or damage from what could have broken those veins.

    Ok I'll check the prop again but I didn't see any other damage.
