hello everyone, i have a 1977 55hp evinrude, im having a little problem changing my impeller out, iv got the lower unit off and and everything else off except the impeller and it frozen on the shaft iv sprayed it with pb blaster and im letting it soak but i really dont think thats going to help, is there a special way to take it off, iv tried putting a flat screw driver under it to pry up with but it doesnt budge any advice or tricks would be helpful. thanks
