    Default Hard impeller swap

    I have a 98 superjet and want to replace the stock impeller with a new solas 13/17 that I picked up. I pulled the pump out but I'm not able to get the old impeller off, I know that it has reverse threads (clockwise to take it off) and I've tried everything but the torch to get it off. Does anybody have any ideas?

    Look at the impellor blades and imagine which direction they turn to propel the ski. (The impellor is designed to 'tighten' itself while the craft is running.) So turn the impellor the opposite direction to loosen from the jet pump shaft. It may require heat as it has been installed for 10+ years. A driveshaft holder tool will make the job easier, contact a local dealer for the tool. (such as Kahuna Powersports)

    Default done!

    A pipe wrench on the impeller with a 3' bar on the end of the pipe wrench did the trick.
