Jacuzzi Identification

How can you tell the difference between the WJ and YJ Jacuzzi jets? What are some of the differences/ is one better than the other?

Is the reverse bucket round or more square. YJs are round the WJs are more square. (trying to come up with a quick way to tell). If there are any tags on the transom adapter or front housing they should say also.
The WJ is the better of the two. The reason being the mixed flow impeller vs. the axial flow impeller of the YJ (propeller in a tube).

Thanks for the info. I will take a look.

Where the nozel bolts to the bowl- the WJ has four square ears that protrude from the base circle for through bolting. The YJ doesnt have these.
