How do you get the impeller off????

[PETE]

I pulled the stator and stuff out yesterday. I did this so that i could blue print my pump, and also because i'm getting a new impeller soon anyway, but I can't seem to figure out how to get the impeller off the drive shaft thing. Do you have to pull the barrings or something. I'm confused :? Instructions please.

Pete,
You will need an impeller tool to remove the impeller.

I don't have one either, so on my Kawi 750, I used a shaft with spline from a CAR's transmission (salvaged) that fits perfectly into the impeller and hold it down on a wise, then turn the "jet pump shaft" with a wrench to loosen the impeller. Makes sense????

Anyway, what do you ride?

Pete, in addition to a shaft holding tool, remember the impellers have REVERSE threads so you should have to turn CLOCKWISE to loosen.

Subwagon, what your saying makes sense, i'll try putting it in a vise, maybe with a bunch of cloths around it or something. I ride a superjet and i'm planning to make it as worked as soul man's :D, with all wamilton's parts :)

Whooa Pete.

To change remove the prop from your Yamaha Superjet you need 2 things. A splined nut to hold the driveshaft and an impeller wrench that fits in the nose of the impeller hub. Unless you have a stock prop with the hexagonal hub you can put a wrench on.

You Superjet is different than Subs Kawi. His prop is threaded onto a short shaft in the stator with splines inside the prop hub.

A yamaha is threaded on the full length driveshaft which is splined at one end.

Don't F%*k up your driveshaft splines and your impeller. The splined wrench is only $15-20. The impeller wrench comes with all new Solas props.

The impellers are on there pretty good. You won't be able to get a good enough hold on the shaft to loosen the impeller without chewing up the shaft.

If you have a stock Aluminum impeller you will might have to heat it with a torch to free it up. If the ski has seen a lot of salt water use you might even have to cut the impeller off.

Soak the thing with some wd40 or anti sieze for a day or two and it will be easier. Don't be surprised when it's hell to get the prop off.

Thanks for the info man, I guess I'll wait until I get my new impeller to get it off. Good thing I'm lazy and didn't try to take it off with a vise.

don't forget to put some anti-sieze on the driveshaft threads when you put the new impeller on.
