3 of the 5 trim bolts broke off the trim cylinder when on the water the other day, the other 2 were stretched and holding to cover to the cylinder. Trim worked great for most of the day. Then shot craps. It's an '88. Not worth taking to a shop. Tried having a welder stick weld nut to what is left of bolts. They are too weak and wont back out. Can't get small enough drill to try to easy out the broken bolts and don't like the idea of removing the motor. Can I plug the fluid line to the trim and still keep the tilt? Throw in a new cylinder rubber seal kit (have one already) and have it welded shut for one more round? Suggestions? Thoughts?

The only fix is a replace.
Yes you can plug the line and have just the tilt.
Remember your damaging things when under way.
Install something in the hole that keeps the motor from pushing against the transom.
Block of wood and sillycone works.

was able to drill out two more. Will have to run a thread chaser/tap die through. Now have 3. One has broken drill bit in it. the other is the top and most difficult to get to. Will see how it goes. If I can get three in good to pull it flush, I should be able to stick spot weld the other two and be good. Any ideas for the stuck drill bit in the middle of one of the bolts? Thanks for your input Jerryjerry05!

Sometimes???? just trying to tap the end of the bit can loosen it just a tiny little bit.
Try to advance and run it backwards.
I have a tiny, center punch that when it gets hit in the right spot it can move the broken bit?
Just don't cut/ drill too much or it might not ever come out.

I worked for 3 hours trying to remove ONE screw on the thermostat cover.
I ended up squaring off 2 edges and making it fit a socket.
Don't know how much you have left to work with, try fitting a TEENY TINY socket?
