Default Impeller Wear

I have a 2005 FX Cruiser HO with 116 hours on it. This is a pick of the impeller on the intake side. Would anyone consider this average wear for the amount of hours on the machine? It still does 58-60mph and very strong out of the hole. Should I have anything to worry about? Thanks!

There is really no "average" amount of wear. I know guys that ride in salt water, in shallow, sandy conditions that have to replace their impellers and wear rings every 50 hours or so. I ride in a very clean fresh water lake and my impeller still looks like new at over 200 hours.

Usually the first sign that you have a problem is poor hole shot........the ski will feel like it is spinning out with no traction at first. Then it gradually picks up speed. If the hole shot is good, then I would not worry about a few nicks and dings. If you want to check to see if it is within spec. You can remove the intake grate and check with a feeler gauge. Or tape a gauge to a stick and check it that way. On your ski you want to see 0.45 mm or less of a gap between the impeller and the housing.

Is there a write up or diy for this job? I replaced the jet pump housing and impeller on my 97 gp760 but I have not on our 05 fx cruiser. It is way way worn and needs replaced. I am the second owner and the original owner has never had it replaced and it cavitates very badly.

Hey Troy, I have seen a few videos on YouTube about the removal of jet pumps and impellers on various skis but not on the fx ho. Sounds like you have had good practice on your other ski. Do you have a pic similar to mine of the impeller just to compare?
