Impeller Shaft

[WetDog]

I have a 2001 SeaDoo GTI and I need to order a replacement Impeller Shaft. How can I tell which Impeller Shaft to buy? It looks like there are 2 different sizes 139.5mm and 155mm.

Is there an easy way to tell from looking at the jet pump housing? I can't remove the Impeller shaft to measure it because I don't have the tool to remove the impeller. I'm planning to order the tool at the same time I order the shaft and other parts to save on shipping.

Any suggestions to Identify the pump size are appreciated.

Cheers!

Go to this sites sponsor seadoowarehouse, and look up your ski and you can find the part number use that when buying a new one.

Sbt site can also be sorted by ski and you can find your part that way too.
