Well... there isn't a "Puller." But, you do need the removal tool. It's a small splined tool that goes into the impeller, and allows you to put a wrench on it to unthread it from the pump shaft.
Nope. The splines are specific to SeaDoo... so if you are looking for one local to you... you will need to check with a seadoo dealer. expect to pay $30 to $40 for one at the dealer... or you get it for $15 from eBay, or your favorite on-line shop.
