Can anyone offer suggestions on how to remove the cover plate off the water pump? After haul-out I wanted to check the condition of the impeller and replace it with a new one in the spring but I can't get the cover off. I removed the 4 screws holding the cover on but the cover appears to have some kind of sealant on the mating surfaces and I can't get anything between the cover plate and the impeller housing to pry it apart. I certainly don't want to score the cover or housing, or worse yet break anything. My E-32-200 has the Universal 25MXP with the Oberdorfer (made right here in Syracuse, NY) water pump. Thanks.
