    Reverse gear making a scary noise

    I've never had an A4 engine before so I just want to make sure I installed this one properly.

    My forward gear clicks in to a position.

    Reverse has no click. The shift control just travels aft. This is normal, right?

    The further aft I set the shift control the louder and more alarming the noise is. Is that normal? How far aft do I need to set the shift control for reverse? Without blowing anything up.

    I attached a video... it's just the sound of reverse.

      Infy, reverse is accomplished via a planetary drive (thus the reduction) and maintaining pressure against the band. The planetary gears are VERY NOISEY when you bring the rpm's up and remember there is a 30% reduction in reverse so you need more rpm's for motion than in forward.

        Thanks everyone! I was worried I may have to yank the engine back out of the boat
