How does the "lock" lever on an Evinrude 25 hp with manual trim work?

I have a1996 Evinrude 25 hp, with remote controls and manual trim, model number: E25ELEOA. When I got it I found that the tilt lock was not functional due to worn/broken parts in the shaft the lever is connected to. I replaced those parts and the tilt lock now works fine.
I am trying to figure out of my trim is broken or functioning that way it is supposed to. Currently, I have to pull the pin out to get the engine to tilt up, and when I let the engine back down it clicks and locks in place on the pin, no matter the location. There is a lever I can move, under the hook that hooks on the pin when down and it swings back and forth, not seeming to matter which position it is in.

I was under the impression that the engine should kick up if I hit an underwater obstacle, stump, etc. With the spring tension on the hook lever that hooks on the pin, I don't see how it could kick up if I hit something.

The lever I was speaking of before, that swings back and forth under the assembly, well I had the impression that it has something to do with reverse, like maybe when it was down it was for forward travel and the engine would kick up if I hit something. If I wanted to use reverse I should move this lever forward, under the tilt pin, to lock the engine in place for reverse operation.

If you look at http://www.crowleymarine.com/johnson-evinrude/parts/49942.cfm
I am referring to parts 74, 76, and 78, with 78 being the lever I can move forward and back, thinking it is for locking for reverse operation. 74 is the actual hook lever that hooks onto the trim pin.

Other notes that may be helpful. The spring, number 103, goes from the center of part 93 to a bar, 56, going across part 78. The spring, 77, goes to 76, the reverse lock, at the bottom and seems stretched awfully tight.


Thanks,
Chris

The reverse lock is designed to lock into position for use in reverse. The reverse lock is spring loaded, so it will still trip if the motor hit something hard in forward if a person forgot to unlock it. Part #78 I believe is a partial tilt hold that flops into position and rests on the pin. Notice part #97 has a spot in it's slot that you manually move into position to lock the motor at full tilt.
Most people run the lock in unlocked position, and lock it to use reverse.

That's the thing here, I have never done anything to use reverse, and have never had the engine kick up when I went into reverse. While this is convenient for me, it makes me think something is not right under there.
Part 97 and 102, are actuated by pins on 95 and 62, which are mated together and "cam" out the slides where that notch is at the bottom.
I run part 78 in vertical, parallel to the engine drive shaft all the time, and have never needed to move it forward, where I assume I should have to move it, for reverse. While the convenience of not having to mess with it is nice, I want to be sure that it will kick up like it's supposed to if I hit something.
Is there a way to test this without driving really fast into a stump or other obstacle?

Thanks,
Chris
