Where can you get the special tool to change the Impeller and is it hard to do?

You might need 2 special tools depending on the impeller that you purchase. One holds the drive shaft and the other will go on your new impeller. Some impellers come with the tool (key) for the impeller and some don't.

Riva should sell all the tools you need.

Some impellers are hard to get off, some are easy. If your has never been off, its probably going to be a little difficult. Do a search, its been outlined many times.

If I remember right the stock one does not need a tool for the impeller - only if you install a Solas impeller will you need an impeller tool (maybe Skat also?). If the stock is the same as a 6.5 NuJet - a large crescent wrench or 1 1/8 inch box end wrench will work even better. Use a little heat and hopefully it will pop right off.

Thanks for the informations! Thinking of order the FX-140 parts from this page.
