Ah ha!
I just went through this not too long ago, to the dismay of my pasengers.
Funny isn't it? You knwo you have a trim problem and you try to correct, but when you nail the throttle the bow sucks itself into the water. Causing all kinds of hairy handling.
The solution is simple, swap out the two hoses going into the pump and you are cured.
The reasson is that there is an impact safety feature on the Aplha trim pumps. A special valve will open up when you strike an unwater object and allow the drive to come up, protecting the drive from damage. When underway with the hoses switched, the pump's emergency valve thinks the boat is striking somthing and it releases it's pressure, making the drive go in.
Oh, and once you switch the hoses, you will have to switch the wires (the green and blue, remember, green grass, blue sky) going to the pump solenoids too, or else your trim switch will work opposite.
Simple fix, trust me and PaulO.
