Like the title says, this is the same exact motor softub uses on its newer 220 gallon softub. The only difference being softub wraps this motor in stainless steel piping. So when my softub motor died I bought this motor and swapped all the new parts over to the old motor housing with the piping wrapped around it. My pump works great now and is quiet. My softub was built in 2016 so I can only vouch for that year of the 220 model.
