Balboa Vico SuperWow Spa & Swim Spa Jet Pumps. These were often labelled 4HP, 3HP, and 2HP. The "HP" was not actual HorsePower, but was used by name only.

All Balboa Pumps marked "4HP" are actually a 2HP pump in Australian spas. See notes below for explanation.
These are a very common pump found on many Spa Industries' brands of spas. (Bullfrog, Signature, Leisurite, Designer, Lanark, SCS Industries, etc) They were often 2-speed pumps with the low-speed wire clipped off, thus actually becoming single speed pumps. If your plug has one wire clipped off, ensure the new pump has the same done!

- Some Spa Manufacturers use a complicated & confusing form of Horsepower measurement that was more commonly used in the USA, called hydraulic horsepower (HP=PSI*GPM/1714). It gives a more impressive appearance, and may give a false impression of performance.
- Australian HP ratings are calculated purely on input power in Watts, which are then converted to HP. (1HP=745.7Watts).
- Balboa & Aquaflo have both released pumps to spa manufacturers that use these confusing power ratings at the request of Spa Manufacturers.
- You can always look at the input ratings and convert back to real HP.
- Rough HP measurement can also be calculated using Ohm's Law (V=IR). These pumps also have an Amperage rating that can be roughly converted back to Watts, and then to Horsepower.
- Furthermore, HP ratings are not an ideal measurement of pump performance anyway! Pump flow curves, which measure flow per metre of head pressure are a far more reliable method of measuring pump performance, especially with the advent of variable-speed DC motors.
