Jacuzzi® Hot Tub Circulation Pump 240VAC 50HZ. Part No.6000-125
The Jacuzzi® Hot Tub circulation pump 240 VAC 50HZ is suitable for all J200 Hot Tubs and all J300 Hot Tubs up to 2012 (in 2012 the 6500-920 pump was introduced for just the J375/J365/J355/J335 models)
This is the Jacuzzi® replacement for previous J200 and J300 circulation pumps. The photos show the upgraded version of this pump (introduced in 2016) so it may not look like the pump you are replacing.
