Does anyone have any idea what could cause a very hard metal hitting metal noise when the drive is operating around 3000 rpm. There is no sound when the drive is operating at a idle speed. The u-joints were replace last winter. The drive is on a houseboat which is in the water until Oct.

how were the PDS shaft bearings?

the U-joints are supported by the PDS shaft

you are greasing the PDS as per the manual, correct?

Are PDS bearings located inside the upper gear housing and if so aren't they lubricated by the lube in the drive?
