I'm fairly new to the surface drives and I picked up a used 36 prodrive a few weeks ago, I test drove it in the water and everything was working good. I started it yesterday to change the oil and heard a noise from the clutch. It sounds like something rattling and it only makes noise in neutral at idle, any increase in rpms it goes away and with the clutch engaged it goes away. Is this a sign that the clutch is on its way out or something is already broken inside?
Thanks

Mine has done it since new in 08 if that helps ya.

Make sure the mounting bolt is tightened down.
