After switching the fluid lines and correcting the wiring i thought the drive would trim up while in motion but it still doesnt, this morning i noticed the drive slowly came down through the night. About half way. This didnt happen when the lines were backwards either. In my other thread about this it was poinred out to me by Don S to check the hoses. They were on backwards, then it would go down when i clicked up. And visa versa, re did the wiring and took it out, boat ran great but the trim still doesnt come up when in motion...

Once you put the hoses on the right way, and it drifted down, that shows that the pressure valve are failing, which is cutting down on the pressure output of the pump. Low pressure is why the drive won't trim up when dual props are pushing it down.

Never tried, not sure if the hoses have the same fittings or not. That would be the only problem with it that I can think of.

You think you're confused, you ought to try to be the one trying to figuring out all this stuff and not being able to look at, hear it or touch it, and only have what you type to go on.

Hah yea i actually know what you mean. Im kind of in your position except over on jeep forum! Lol. But yea i might take the other pump out to the lake and see if it works now, since its easily accesible i could change it on the water
