Response to Hi Mike, this pump would be underpowered compared to your Jacuzzi 1MFS Magnum Pump. Our suggestion would be the PL2602 PureLine Prime 1.5 HP Pool Pump the plumbing ports on the PureLine Prime will not be in the exact same position as your Jacuzzi Magnum so you will have a little re-plumbing but it should be nothing major.
