Sorry I waited to upgrade
5/5
Great product, easy to upgrade. Much quiter then the old pumps, and easy to rebuild.
This upgrade kit allows you to install the new Whisper motor on an existing pump that has the old motor #310245 which is no longer available.
You must install all the new parts to use this motor. For the 24V version see 385311424
