tilt/trim drain plug

Hi all! I have 1974, evinrude 115hp.

Problem is I pulled the t/t drain plug with the motor fully in the raised position.  Of course it came down, blew the plug out and oil everywhere.

I can not get the plug back in enough for it to seal. Is there something inside that is stopping it from going back in? Did I lose something when the plug came fully out?

Any help is greatly appreciated !

Normally inside of trim pumps, the check valve should screw into place. Behind that  is normally a shuttle pin with a spring. That style trim unit does not have a repairable trim pump, just replacement. You may have to find a junked engine or a used part from a long established dealer as the last use of that trim system was about 1976 or '77.
