Bravo Drive Coupler Grease Cup?
So I'm in the process of putting a couple new motors in the boat. Pulled the drives/motors and in the process of undressing the back of the motor (coupler, housing, flywheel, etc), these small cups where sitting loosely between the coupler and flywheel. It appears there might have been a plastic sleeve over the outside to facilitate a better fit at one time, any help identifying these would be appreciated.

What engine model and year are you working on?
Can't say that I've noticed that part before but looking at a photo of a similar type coupler backside, it looks like yours maybe sticking out further then the one linked below which is a big block...Plus you can see some sort of plastic looking part.

Are both couplers doing/look the same?

Hi LMD, both motors had them and they are 496 HOs with Imco extension boxes (so longer drive shafts). I couldn't find anything online, but it looked like they might have been intially installed to prevent grease from discharging into the cavity in the end of the crankshaft or void between the coupler and flywheel?

This is the stock OEM 496 MAG and the HO 496 thru out all serial number runs that was used by Mercruiser pic to compare

They use to come with shipping dust cover cap.
