    440 swap to 550 motor identification

    Hey Guys,
    I'm looking to do a 550 swap into my JS440 hull. I found a guy selling a motor but I want to be sure its a 550. How can I identify the 550 motor? Because I read you can keep the bottom end of a 440 which has the motor id and put in the 550 top end. Any advice would be appreciated. Thanks!

    Are you saying that this is a 440/550 motor or a 550?
