How to tell if you need a new impeller?

How to tell if you need a new impeller

If your Jet Ski, Sea Doo, Yamaha or Honda has a problem when you take off from a dead start (slipping)? Then you need to check the pump area to see if you have an obstruction. First look through the exit nozzle with a flash light. If you see rocks or debris in the pump veins. Odds are that is the problem. You also want to look at the back of the impeller blades to see if they are damaged/dinged. If you see dings or it looks damaged the odds are you need a new impeller and possibly a new wear ring. If you don't see anything from the back, then look from the front of pump to see if you have any rope, string or weeds attached to the shaft in front of impeller.

If your impeller is old and worn out? this would also create a slipping feeling when you take off.
