Looks like you are running that motor without water? You will need a new impellor, but thats the least of you problems right now! Did you try a big hammer and wood like suggested? That head is ruined now anyway.

drilled out and cut with grinder tried a puller and acetylene torch it was welded in with corrosion and one bolt broke again Basically had to cut and drill around the bolts get it off and got my heli coil in there now . but have not went past that part yet, the water was just going from on cylinder to others cylinder you could see the path (trail ) on the old head gasket left by corrosion color like dust sand. Hey how did it even run and sometimes ran real fast . Huston we a new power source you utilize and you figure it out.

I can not see , feel or hear your motor.----Up to you to post some information.---Post compression test values.----Does spark jump a gap of 3/8" ( 1 cm ) on a test device.-----Does manual fuel pump go hard when operating it ?

i got engine back together and ran it and was not pumping water took lower off and it looks like it sheared the impeller key did not see a key in there so got try get a key and how about that gasket in the picture what will that cause can i use it like that or Will this give water a chance to get into the cylinder if that gasket is bad.

Get your self a complete water pump kit and a new exhaust housing gasket if you plan to move forward with the project.

The key should be there somewhere,----Look under the bottom plate of the pump.
