Tilt and Trim question

[BayouRunner]

I have a 1990 Mercury 115. When at w.o.t., I can only trim up so high, and that's it. On the trailer, or at idle, I can trim to where the prop comes out the water (I don't do that at idle, but I could). Once I get going, the trim only goes so far. Why? Is there a limit switch that wasn't working, and all of a sudden is now? When I first got the boat, I could trim up as high as I wanted at w.o.t. On the trailer trim all the way up and all the way down with no problem.

Sounds normal. When at High throttle it is only a trim. Otherwise it is a tilt.

Will check the oil...prob needs to be replaced since it seems the previous owner didn't prescribe to the preventative maintenance lifestyle.

So at w.o.t., I can only tilt the motor so high? Funny how it tilted higher about 3 trips ago. Maybe it was malfunctioning then, and is how it should be now?
Next to regulate and tune the carbs...my speed sux.

This is cut from service manual explaining how tilt and trim works. It's not from your exact year but I think yours should work the same.
