This is not an assembled or aftermarket pump. It is a brand new OEM Aqua Flo/Gecko pump with a 2 Year warranty.. The pump you order needs to say Aqua Flo by Gecko or it is not the genuine article
Aqua Flo FMXP2 2.0 HP 230 Volt 2 Speed Pump
Inlet and outlet measure 3" outside diameter.
Note: Your pump motor may say 3.6 or 4.0 HP SPL. SPL stands for special and can make things a bit misconceiving. It is used as marketing HP to help sale off the showroom floor and allows the spa manufacturer to get by with calling it something larger then it is really is. Motors should be matched by their amperage and not the HP. In this case the motor is actually 2 HP falling in the window of 8.5 Amps
