The 4 HP Waterway Executive 56 # 3721621-1D is a durable, high-performance pump that delivers reliable water flow efficiently. Always select a replacement pump with the same part number as the Waterway part number. Pumps are rated on amperage not neccesarily horsepower. New pump amperages will vary slightly depending on the supplier of the actual motor. The RPM's remain the same with the same performance. Compatible replacement for a Gecko XP2e Model 0533-4012, GK-0800-3990000, Gecko 0543-4000-5 and Hydropool 6505155.
The far bolt was worn so I had to cut it. I then used a toggle prepositioned in the new pump which dropped into the hole as I squeezed the pump in place. Look at the diagram on the pump for the correct wiring. I used an Oil filter wrench to loosen the water pipes. Probably a good idea to order new O ring seals. Very happy with the pump although delivery was a little slow.
Easy to hook up and quiet as well
my Spa works like new !! thanks !
Perfect fit. Talked directly with a someone to double check before ordering. Was very helpful.
Delivered in two days to my door.
Only issue was the bracket was bent to affix motor. Was an easy enough adjustment.
This pump was $200 more everywhere else I looked.
Received product within 24 hours. Was the exact fit. Hot tub up and running in about an hour.
Good price. Works well. Ordered 1 day and received the next. Couldn't ask for a quicker turn around!!
Tech on the phone helped me through the correct motor choice.
This was a replacement motor for the original Gecko I had in my hot tub. It fit perfectly, runs cool and quiet.
Had to make a small adjustment to the spa pack as this pump was a touch wider than the Gecko pump I had, but overall works perfectly. Gentleman I spoke to on the phone was very friendly and helpful. Highly recommend Canada Hot Tub Parts.
