If you are going to work on your own ski, you are going to need some tools. After a basic set of hand tools there are some special tools just for working on jet skis, and these vary by jet ski manufacturer.
You are going to probably run into this first when working on pumps.
SPECIAL PUMP TOOLS – if you are going to remove the impeller and shaft, you are going to need a tool to turn the IMPELLER.
I have seen some interesting improvisions, but the correct tool is the impeller tool.
You will need to put the impeller shaft into a vice. You remove the cone on the back of the pump for access to the shaft. To do this, on some models you will need a 10mm hex wrench, on some models the end of the shaft is square.
Once the impeller shaft is held, you insert an impeller tool into the impeller, and turn it (using a 17mm socket and a 6 foot
breaker bar). (SEADOO IS NORMALLY STANDARD THREAD -RIGHTY TIGHTY)
When used right, these tools make removing the impeller an easy job.
YOU MUST use a long breaker bar. This is not due to the amount of energy you need, but the quality – smooth even pressure – provided by the long breaker bar.
YOU MUST use a very good vice. The vice I use cost nearly $1000 new – now, you don’t need one this mean, but a $39 HF vise will fail when assaulted with a 6 foot breaker bar (yeah, I’ve got some broken vices).
NOTE: I do not suggest using heat or anything else other than good clean power to remove impellers. You need smooth, even power. DO NOT use impact drivers or other power tools.
