Model B4415/4415UI

Body measures 4.75″x2.75″ and has spade terminals (if you have wire leads on your motor, you need a different motor!)

UPDATE 2/26:: Keystoker has these gear motors redesigned in 2025 and they no longer include the small white fan or the shaft for the fan. The motor is cooled internally.
