Often had A. O.  Smith Century LASAR Pool / Spa Motor. Used in many older Lanark Heritage Maax and other brands. The original Waterway Executive 48 & 56 pumps are no longer available. When replacing, do not go by HP, because the USA method, and the Australian method of labeling horsepower is different. Email us if you are unsure. 

No longer available.
