Problem with powerhead removal

[High Wire]

I'm trying to remove the powerhead from my 1988 Evinrude 9.9 short shaft due to a cooling water blockage at the powerhead inlet. I have removed the 6 powerhead bolts, and 3 rubber mount bolts, the carb, the cyl head, and port side byp*** plate. Also disconnected the throttle cable, various hoses and shift interlock linkages. I can't see anything else holding the powerhead on except the gasket. I tried prying up and knocking side to side with a rubber mallet with no luck.
What am I missing?

Problem solved. Needed bigger and better prybar!
Cooling blockage was the rubber inlet grommet all crushed up. Smoking gun!
