Problem removing Water Pump base on 50hp outboard

[craig newton]

Have a 2004 Mercury 50hp 4 stroke EFI. Decided to change the bottom plate as well as the water pump base this year with my routine impeller change. I inserted a screwdriver in each recessed spot at the top of the base and started to pry. I believe it has been in there since day one because it wasn't budging. A little more pressure and both screwdrivers ripped the top out of the holes they were in, still without moving the base. Can someone please tell me how to get that thing out of there?
I will try to upload a picture when the site administrator resolves the issue preventing me to do so.

Some idiots glued the parts together. Probably because they leaked too badly.

I bought this engine brand new on a 17' Alumaweld and am still the only person to work on the lower end.

Well your going to need a new one first. Then apply 10psi air into unit, use 2 coated decking screw 3.5 inches long, thread into base and use 2 cats paw pry bar and pull up on it evenly

Well the factory or dealer did a terrible job. 2004 engine is out of any factory help if further problems arise. 20 trouble free years is a excellent engine.
