need help

This is on my 1971 C22. Just got the boat and know nothing about this motor mount. It wont budge? I put a lot of force on it and nothing... and was afraid to put more cause the vertical pole seemed like it was going to start bending. I know most have a lock but I don't see anything that...

I have a 1994 expo solar sailer, 14'-6". In a blow it was rocking at it's mooring and the mast sawed thru the deck and fell down. Not sure how to repair this. the mast step pulled out and there is no apparent blocking to attach it to and no reinforcement. Any ideas would be welcome. Phone #...
