Sucked Something Up....Help Assess the damage
Well, I went out today to test the ski out and really didn't get to do much of anything. I warmed her up for a good while and once I started going about 7000 rpms I feel something get sucked up. 3 of the veins in the pump are pretty beat up. Do I just need to buy a new impeller duct so that I have one with good veins on it or do I need to also buy any other parts or look in other areas? Also, does anyone have one in good condition that they want to sell or should I just buy new. The impeller looks to be in good condition. Check out the pics. They are not the best cause they are from my phone.

Almost looks like cavitation burn.

I definitely felt something get sucked up. I didn't do any hard starts from a standstill. They were all from a rolling start. Maybe it happened in the past but I just looked at the pump a week ago and it looked perfectly fine.

Sure seems like the prop would be damaged if something became wedged between the prop and stator enough to do that damage.
What you felt get sucked-up--did it just pass through or did you have to remove it?

You may have sucked something up but that is without a doubt cavitation burn. You're running stock pump with E1/Motec.....

I went back to the dock and couldn't see anything. I actually saw something in front of me at the last second, which looked like a stick. I tried to move but I couldn't. As soon as I went over it I heard a noise or something getting sucked up. I pulled a log and my afr wasn't reading anything the whole ride so that sh!t the bed. I'm frustrated.

Well, how do I fix it? What parts do I need?

Sounds like cavitation burn and I've read of two ways to fix this--Skat pump or Sea-Doo pump.
From what I've read here on the hulk, the differences are the Doo pump works a bit better and will let you have more prop options (does this have anything to do with it working better?) and this option can be a bit cheaper as it uses some stock parts (ebay). Talk to Dan at Jet Draft as he seems to be leading in this area.
Skat setup can be ordered through Jerry's store and this has it's advantages. Seems like a (very small amount) more expensive than the Sea-Doo pump option.

Is anyone running the E1 with an ecu and still using the stock pump? I don't know if I have the cash right now for a new pump. I just checked and it did seem that the one edge of the impeller was nicking the vein.
