Has anyone in the group had experience with a rattling BMW MKII sterndrive
unit or an early Volvo which is similar. Mine rattles loudly after a run on
the plane when you come down to idle speed. It wont rattle in neutral till
you get the revs up to about 1800 then the rattle comes back.

It has no decernable rattle under load, just idle after a planing run. The
unis and gimbal bearing have already been replaced. When I dont use the boat
a few days and start up it is quiet at first, but always comes back.

Anyone?

Thanks
Cam
