    Default Raw water pump drive

    Hi all, We have a 1980 80 hp motor with a odd drive connector for the raw water pump. 2 metal plates with a plastic plate in between. Old style Lovejoy? Anyway, we are stuck in Mobile Bay on way to Tampa and looking for help. The pump bracket cracked, got a replacement installed it. Now when motor is running, pump wobbles I tried making a new center piece for the drive connection out of starboard with slightly larger holes but still get the wobble. The pump side plate ( with 2 pins on it) is worn around the keyway, probably case of wobble. High pressure pump side ( splined with 2 pins ) is in good shape. Anyone know where to get a replacement? Upgrade?
    As I said, we are stranded motorless in Mobile Bay and want to get to Tampa before New Years. Any suggestion?

    Hi, Sorry to say this coupling is no longer available. However you may find the pump side coupling on ebay It was a browning CHFS2X5/8 A local machine shop can make you a nylon centerpiece. For the future suggest a crankshaft driven pump off the front of the engine. Call American Diesel 804 435 3107 for details.
