    Welcome to the Hulk!

    Liberty is just the branding that Polaris used for their engines, it doesn't actually mean much.

    The MSX 150 uses a 150HP rated Weber (German built) two cylinder, turbocharged 4-stroke engine. Unless someone went to a lot work effort, that would be the same engine that was in that hull from the factory.

    There were a few updates and service bulletins related to those engines, so I would expect your replacement engine had all, or most of, the updates.

    Was your engine replaced under warranty?
